Abstract
The talk will focus on two kinds of planar spectrometers; (a) SOI AWG and etched grating and (b) PLC spectrometer based on spatial heterodyne spectroscopy (SHS). Athermalization of SOI AWGs will be described. PLC-SHS is a kind of Fourier-transform spectroscopy. Operational principle and current progress of PLC-SHS will be described.
