Abstract
Multi-wavelength integrated light sources are key devices for future large scale wavelength division multiplexing (WDM) systems. One of important issues is precise control of lasing wavelength of each element. Large temperature sensitivity of lasing wavelength is also a remaining problem. Recently, wavelength stabilization of semiconductor lasers using strain was demonstrated [1]. Also, wavelength trimming technique was proposed for post-process precise control of wavelength [2].
