Comb Using Photonically Integrated Devices (CUPID)

Optical frequency combs play an essential role in modern timekeeping and metrology. To date, however, frequency combs are primarily used in laboratories, owing to their size, weight, power, and cost (SWaP-C) and fragility. To operationalize the technology, Vector Atomic and Harvard University will design an erbium (Er) fiber Comb Using P hotonic Integrated Devices for supercontinuum generation and self-referencing. CUPID will combine the robust Er fiber comb architecture with an integrated nbsp;photonics module for supercontinuum generation and self-referencing. CUPID will provide lt; 10-17 excess fractional instability at 1 s, in a compact package at low power and manufacturing cost.
