Heart‐Like Mode Profile in a High Depth‐to‐Width Ratio Non‐Suspended Nano‐Trapezoidal Silicon Waveguide for Near‐Infrared Gas Sensing
Mingquan Pi, Xuan Mao, Yuting Min, Ningbo Ma et autres
ABSTRACT The mature near‐infrared on‐chip integration technology and low‐noise detector contribute to the development of optical waveguide gas sensors. The external confinement factor (ECF) governs light‐gas interaction efficiency in on‐chip infrared waveguide gas sensors. While suspended waveguides achieve ECFs exceeding 100% (surpassing …
