- lang: eng
text: The monolithic growth of III–V materials directly on Si substrates provides
a promising integration approach for passive and active silicon photonic integrated
circuits but still faces great challenges in crystal quality due to misfit defect
formation. Nano-ridge engineering is a new approach that enables the integration
of III–V based devices on trench-patterned Si substrates with very high crystal
quality. Using selective area growth, the III–V material is deposited into narrow
trenches to reduce the dislocation defect density by aspect ratio trapping. The
growth is continued out of the trench pattern and a box-shaped III–V nano-ridge
is engineered by adjusting the growth parameters. A flat (001) GaAs nano-ridge
surface enables the epitaxial integration of a common InGaAs/GaAs multi-quantum-well
(MQW) structure as an optical gain medium to build a laser diode. In this study,
a clear correlation is found between the photoluminescence (PL) lifetime, extracted
from time-resolved photoluminescence (TRPL) measurements, with the InGaAs/GaAs
nano-ridge size and defect density, which are both predefined by the nano-ridge
related pattern trench width. Through the addition of an InGaP passivation layer,
a MQW PL lifetime of up to 800 ps and 1000 ps is measured when pumped at 900 nm
(only QWs were excited) and 800 nm (QWs + barrier excited), respectively. The
addition of a bottom carrier blocking layer further increases this lifetime to
∼2.5ns (pumped at 800 nm), which clearly demonstrates the high crystal quality
of the nano-ridge material. These TRPL measurements not only deliver quick and
valuable feedback about the III–V material quality but also provide an important
understanding for the heterostructure design and carrier confinement of the nano-ridge
laser diode.

text: Introducing spin-polarized carriers in semiconductor lasers reveals an alternative
path to realize room-temperature spintronic applications, beyond the usual magnetoresistive
effects. Through carrier recombination, the angular momentum of the spin-polarized
carriers is transferred to photons, thus leading to the circularly polarized emitted
light. The intuition for the operation of such spin-lasers can be obtained from
simple bucket and harmonic oscillator models, elucidating their steady-state and
dynamic response, respectively. These lasers extend the functionalities of spintronic
devices and exceed the performance of conventional (spin-unpolarized) lasers,
including an order of magnitude faster modulation frequency. Surprisingly, this
ultrafast operation relies on a short carrier spin relaxation time and a large
anisotropy of the refractive index, both viewed as detrimental in spintronics
and conventional lasers. Spin-lasers provide a platform to test novel concepts
in spin devices and offer progress connected to the advances in more traditional
areas of spintronics.

text: In this paper, we present a confocal laser scanning holographic microscope
for the investigation of buried structures. The multimodal system combines high
diffraction limited resolution and high signal-to-noise-ratio with the ability
of phase acquisition. The amplitude and phase imaging capabilities of the system
are shown on a test target. For the investigation of buried integrated semiconductor
structures, we expand our system with an optical beam induced current modality
that provides additional structure-sensitive contrast. We demonstrate the performance
of the multimodal system by imaging the buried structures of a microcontroller
through the silicon backside of its housing in reflection geometry.

text: Although there are numerous design methodologies for the LLC resonant converter,
they often do not consider the possibility of input voltage adjustment. In the
proposed concept, a modular multi-level converter (MMC) is used to step-down the
three-phase medium voltage of 10 kV, and provide up to 1 MW of pure DC power to
the load consisting of electrolyzers for hydrogen generation. Therefore, each
module is extended by an LLC resonant converter to adapt to the specific electrolyzers
DC voltage range of 142...220 V and to provide galvanic isolation. In order to
achieve a high efficiency for a wide range of load conditions, the input voltage
of the LLC converter is adjusted between 600 V and 770 V while operating at resonance
or close to resonance. The parameters of the 11kW LLC resonant converter with
an integrated leakage inductance are systematically optimized to maximize the
efficiency for all loads while achieving zero-voltage switching. For a fast estimation
of eddy current losses, a new method is proposed, which uses a single FEM simulation
to fit newly developed loss equations. The calculated average efficiency is 97.8%.
The prototype of the LLC converter reaches a peak efficiency of over 98% at resonance
at half load which is similar to the precalculated value.

text: This paper presents a broadband track-and-hold amplifier (THA) based on switched-emitter-follower
(SEF) topology. The THA exhibits both large- and small-signal bandwidth exeeding
60 GHz. It achieves an effective number of bits (ENOB) of 7 bit at 34 GHz input
frequency and an ENOB of >5 bit over the whole input frequency bandwidth at sampling
rate of 10 GS/s. Much higher sampling rates are possible but lead to somewhat
worse performance. The chip was fabricated in a 130 nm SiGe BiCMOS technology
from IHP (SG13G2). It draws 78 mA from a -4.8 V supply voltage, dissipating 375
mW.

text: In this paper we present the system and circuit level analysis and feasibility
study of applying microwave Radio Frequency Identification (RFID) systems with
multipleinput multiple-output (MIMO) reader technology for tracking machining
tools in multipath fading conditions of production environments. In the proposed
system the MIMO reader interrogates single-antenna tags, and a high RFID frequency
of 5.8 GHz is chosen to reduce the size of the reader's antenna array. According
to the requirements dictated by the performed system analysis at 5.8 GHz, a low
power fully integrated analog frontend (AFE) is designed and fabricated in a standard
65-nm CMOS technology for low power passive transponders. Performance of the Differential
Drive Rectifier (DDR) topology as the core of the energy harvesting unit is investigated
in detail. A multi-stage DDR power scavenging unit is dimensioned to provide a
1.2 V rectified voltage for 20-30 kQ load range, with a high power conversion
efficiency (PCE) for high frequency and low input power level signals. The rectified
voltage is then converted to a 1 V regulated voltage for the AFE and the baseband
processor with 30 to 50 μW of estimated power consumption. Transistors with standard
threshold voltage (VT) have been used for implementation. Measurements of the
fabricated multi-stage configuration of the circuit show a maximum PCE of 68.8%
at -12.46 dBm, and an input quality factor (Q-factor) of approximately 10. Amplitude-shift
keying (ASK) demodulator and backscattering modulator with 80% modulation index,
operating according to EPC-C1G2 protocol are applied for data transfer. The AFE
consumes less than 1 μW in the reading mode. The AFE tag chip is 0.55 × 0.58 mm

text: In this paper we present a new system concept for an optoelectronic wireless
phased array system. Like in a conventional phased array system with optical carrier
distribution, optical fibers are used to distribute the carrier from the basestation
to the wireless frontends. However in contrast to prior concepts, we propose to
use an optical IQ return path from the wireless frontends back to the basestation.
Furthermore, we reuse the optical carrier signal for the IQ return path which
allows to avoid local oscillator lasers in the wireless frontends and reduces
the hardware effort significantly. The system concept allows to integrate all
components of an optoelectronic wireless frontend in a single chip using silicon
photonics technology.
