Optimization of tunable silicon compatible microring filters
… timing errors in the sampling of the signal. Thermal tuning is used to compensate for any fabrication errors or environmental temperature fluctuations that might lead to shift in the resonant frequency. With the optimized heater design and the proper closed feedback temperature control …

Low Loss Integrated Photonic Devices and Their Applications in Astrophotonics and Quantum Information
… features an extinction ratio of 58 dB without thermal tuning and 50 dB with thermal tuning. A TM noise reduction technique is also shown to help realize the maximum extinction ratio.

Automated wavelength recovery for silicon photonics
… ratio, a 1.22-dB insertion loss and a record-low thermal tuning (4.9-[mu].W/GHz) of a high-speed modulator is achieved. We demonstrated a new L-shaped resonant microring (LRM) modulator that achieves 30 Gb/s error-free operation in a compact (< 20 [mu]m²) structure while maintaining single-mode …

Investigating thermal dependence on monolithically-integrated photonic interconnects
… architecture and system perspectives. High thermal sensitivity of the essential optical ring resonator imposes constraints on the applicability of optical links in the electro-optical systems. To investigate the thermal dynamics as well as to develop advanced ring thermal-tuning mechanisms, …

Frequency-tunable second-harmonic submillimeter-wave gyrotron oscillators
… frequency. An unprecedented continuous frequency tuning range of more than 1 GHz has been achieved in both a 330- and a 460-GHz gyrotron via magnetic field tuning or voltage tuning. The 330-GHz gyrotron has generated 19 W of power in a cylindrical TE4,3,q mode from a 13-kV 190-mA electron beam. …
