Abstract
A tunable laser, including: a gain section configured to provide an optical gain for lasing; a multi-channel splitter section configured to split an input signal into multiple outputs; and a multi-channel reflection section, the multi-channel reflection section including multiple arms of unequal lengths and configured to provide an optical feedback and a mode selection function for the laser to work. The gain section, the multi-channel splitter section, and the multi-channel reflection section are sequentially connected in that order. The facet of the gain section away from the multi-channel splitter section is an optical output facet of the laser. When arranging the multiple arms of the multi-channel reflection section in an order according to their lengths, length difference between adjacent arms are unequal. Facets of the multiple arms away from the multi-channel splitter section are coated with reflection films.
