A silicon-photonic interferometric wavemeter and biochemical sensor based on phase demodulation with a novel multitone mixing scheme is presented. The method is robust to modulation depth variations and light-intensity noise, and its simple two-mixer configuration allows for real-time demodulation using a digital signal processing system.

Abstract
A silicon-photonic interferometric wavemeter and biochemical sensor based on phase demodulation with a novel multitone mixing scheme is presented. The method is robust to modulation depth variations and light-intensity noise, and its simple two-mixer configuration allows for real-time demodulation using a digital signal processing system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
