Abstract

A tunable MSM photodetector using an integrated thin film NiCr microheater has been designed for photonic integrated circuit, optical interconnect, and access network transceivers. The tuning sensitivity of the photodetector is 1.4nm/mW.

An integrated tunable MSM PD based on Indium Tin Oxide (ITO) that is fabricated on Si and InP. Tuning is achieved by using a Nickel Chromium (NiCr) microheater which is collocated on the opposite side of the PD substrate. This design presents an alternate solution which does not require an engineered resonator or quantum well.

The integrated MSM PD and microheater were designed using L-Edit and COMSOL software. The MSM PD finger width was 2µm with a finger spacing of 5µm.  The detection diameters ranged from 150µm to 300µm. The heater design was spiral in shape with a coil width of 10µm with a spacing of 10µm.
