Zhang, B, Qubaisi, K A, Cherchi, M, Harjanne, M, Ehrlichman, Y, Khilo, A N & Popović, M A 2020, ' Compact multi-million Q resonators and 100 MHz passband filter bank in a thick-SOI photonics platform ', Optics Letters, vol. 45, no. 11, pp. 3005-3008 . https://doi.org/10.1364/OL.395203
We demonstrate ring and racetrack resonators with Q s of 3.8 to 7.5 million and 100 MHz bandwidth racetrack resonator filters, implemented in a thick silicon-on-insulator foundry platform that features a 3 µm thick device layer. We show that special

This paper is concerned with a process of transforming the mathematical representation of a multithreshold comparator to electrooptical implementations. The basic comparator converts an analog input into one of two levels at its (binary) output. If t

We propose an on-chip triply resonant electro-optic modulator architecture for RF-to-optical signal conversion and provide a detailed theoretical analysis of the optimal “circuit-level” device geometries and their performance limits. The designs

The efficiency of optical sideband generation with a microring resonator modulator as a function of modulator parameters is studied taking into account the photon dynamics inside the resonator. The best achievable modulation efficiency is determined

We propose doubly and triply resonant electro-optic modulators for efficient narrowband RF-to-optical signal conversion. Using a dual-optical-cavity design, we predict 30dB higher conversion gain than single-cavity modulators, and another 5–10dB us

Attempting to apply photonic technologies to data processing has been taking place for several decades. Yet, their implementation in practical systems remained limited and failed to penetrate practical processors. Many demonstrated optical devices re
