1.5-μm-radius high-Q silicon microring resonators
2008 Edition, May 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We show cascaded silicon microring resonators with 1.5-mum radius critically coupled to a narrower waveguide. A coupled Q of 9,000 is achieved. Devices are fabricated with the widely-available SEM-based lithography system using a stitching-free design.

2007 Edition, October 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We demonstrate as low as 3.88 plusmn 0.57 dB/cm propagation loss at telecom wavelengths in compact silicon microring resonators with small bending radii of 5 mum and a waveguide core cross-section of 500 nm times 250 nm.

2018 Edition, October 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We investigate silicon microring resonators embedded with Ge2Sb2Te5. The phase change is induced all optically by using a sequence of optical pulses. The tuning is non-volatile and repeatable, which can be employed for optical trimming.

Large bandwidth continuously tunable delay using silicon microring resonators
2009 Edition, September 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We demonstrate a distortion free tunable delays as long as 72 ps with a 10 GHz bandwidth using thermally tuned silicon microring resonators. The device is compact measuring only 30 µm wide by 250 µm long.

Polarization diversity silicon microring resonator for WDM ADD-DROP filtering

We have demonstrated a polarization-diversity silicon microring resonator with a low PDL of <;1 dB, which is successfully used for polarization independent ADD/DROP of a 10 Gbit/s channel in a 10 λ × 10 Gbit/s WDM signal.

Lateral dopant diffusion length measurements using silicon microring resonators
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

An electro-optic device in silicon such as a photodetector and a modulator requires doping to realise desired junctions. Doping Si is typically done using ion-implantation or thermal diffusion process. Both the processes rely on hightemperature anneal to either activate or drive the dopant...

Active silicon microring resonators using metal-oxide-semiconductor capacitors
2004 Edition, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose an injection-type active silicon microring resonator using metal-oxide-semiconductor capacitors. Our simulations reveal a modulation bandwidth exceeding 2 GHz, a resonance shift of 0.5 nm, and an extinction ratio exceeding 20 dB.

Compact low-threshold hybrid silicon microring resonator lasers
2010 Edition, January 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Low-threshold lasing is achieved on compact hybrid silicon microring resonator devices (radii: 7.5, 12.5, 25 μm) through both optical and electrical pumping. The limiting factor in scaling down for sub-mA operation is the thermal impedance.
