  bibo_abstract:
  - Integrated photonic-assisted signal processing has multiple applications such
    as signal amplification, multiplexing, and high-Q filtering in optical communication
    systems, optical sensing systems, and also microwave photonics. We will review
    recent works on integrated photonic-assisted signal processing for sinc-shaped
    Nyquist pulse generation, high-bandwidth Nyquist signal detection with low bandwidth
    devices, arbitrary waveform generation and measurement, and on-chip photonic frequency
    decoding. However, in such photonic integrated circuits (PICs), the photonic components
    are placed very close to each other on the chip, resulting in thermal crosstalk
    which degrades the system performance. Air-filled oxide and deep trench designs
    have proven to be very effective in mitigating the thermal crosstalk for various
    frequently deployed photonic devices like Mach-Zehnder modulators (MZMs), ring
    resonators, optical switches, and photodetectors designed on a standard silicon-on-insulator
    (SOI) platform. In this chapter, we will additionally review the basics of optical
    signal processing and some results for such trench-enhanced thermal crosstalk
    resilient circuits.@eng
