Abstract

The mechanisms of wavelength tuning in the multisection distributed feedback (DFB) and distributed Bragg reflector (DBR) lasers are discussed and a review is made of recent progress. It is shown that the maximum wavelength tuning range is limited by the maximum refractive index change in a semiconductor.
