Optical frequency synthesizer
WebOPLL-based optical synthesizer. The device includes a compact, low-power coherent optical system involving a 60-nm-tunable LO laser, couplers and photodetectors monolithically integrated on a standard InP/InGaAsP material platform, as well as an integrated Kerr optical frequency comb (OFC) generator operating as a frequency reference. The Webrevolutionary advance in optical frequency synthesis. In this work, we describe a chip-scale optical resonator enabled synthesizer (CORES), shown in Fig. 1. This approach is aimed at fully integrating active and passive components (including control electronics) of a comb-based optical frequency synthesizer on a silicon (Si) chip having
