Abstract:Highly-integrated spectrometers with performance excellence are extremely desired for various applications, such as consumer electronics and unmanned aerial vehicles. In this paper, an ultra-compact monolithically-integrated single-microring spectrometer on silicon is proposed and realized with a high resolution as well as a broad working window. In particular, an innovative scheme of utilizing the free spectral range (FSR) dispersion for a single-microring and strategically inducing resonant peaks red-shift m… Show more
