Article Synopsis
- - Recent developments in programmable photonics integrated circuits show promise for applications in deep neural networks, quantum computing, and FPGAs, but are hampered by slow tuning speeds and high power consumption of current phase shifters.
- - The paper presents the memresonator, a new type of phase shifter made from a metal-oxide memristor integrated with a microring resonator, featuring impressive characteristics like 12-hour retention times and low switching energy.
- - Fabricated on a heterogeneous III-V-on-Si platform, these memresonators support diverse optoelectronic devices and facilitate in-memory photonic computing, enhancing the scalability of integrated photonic processors.
We report a heterogeneous GaAs-based quantum dot (QD) avalanche photodiode (APD) on silicon with an ultralow dark current of 10 pA at -1, 3 dB bandwidth of 20 GHz and record gain-bandwidth product (GBP) of 585 GHz. Furthermore, open eye diagrams up to 32 Gb/s are demonstrated at 1310 nm. The k-factor has been measured for these devices to be as low as 0.
