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.","lang":"eng"}],"publisher":"Springer Nature Switzerland","_id":"65600","user_id":"44271","status":"public","place":"Cham","oa":"1","citation":{"mla":"De, Souvaraj, et al. “Integrated Photonic-Assisted Signal Processing and Thermal Crosstalk.” <i>Metrology for THz Communications</i>, Springer Nature Switzerland, 2026, doi:<a href=\"https://doi.org/10.1007/978-3-032-01986-8_20\">10.1007/978-3-032-01986-8_20</a>.","ama":"De S, Mandalawi Y, Das R, Weizel M.
