Silicon photonic on-chip trace-gas spectroscopy of methane
Abstract
We demonstrate a silicon photonic chip sensor for absorption spectroscopy of methane near λ=1651 nm. Noise analysis demonstrates 8.5×10-4 Hz-1/2 minimum fractional absorption and Gaussian noise performance with 20 ppmv detection limit at ∼103 s.
