Title:
RESONANT DEVICE IMPROVEMENT IN PICS USING SPARE DEVICES TO REDUCE POWER REQUIREMENTS
Document Type and Number:
WIPO Patent Application WO/2022/081278
Kind Code:
A3
Abstract:
A Photonic Integrated Circuit, PIC, (20) includes N Ring and Disk type Microstructures, ROMs, (11, 12, 13, 14, 15) N is an integer and greater than 1; at least one spare RDM (22), wherein each RDM (11, 12, 13, 14, 15, 22) operates spectrally in a periodic nature and has its spectral operation vary by temperature; and circuitry configured to handoff any of the N ROMs (11, 12, 13, 14, 15) and the at least one spare RDM (22) for spectral operation based on a current temperature. For the handoff, the at least one spare RDM (22) is unlocked spectrally and is tuned and locked to a frequency of interest of a current RDM based on the temperature, and the current RDM is unlocked.
