Paper Abstract

In this paper, we present wide range tunable semiconductor lasers using multiple quantum wells of different widths. Conventional semiconductor-laser gain medium using the quantum-well structure for the wavelength near 0.8 micrometers has only 50 meV bandwidth. Using quantum wells of different widths could significantly broaden the gain bandwidth, so broadband tuning of the laser could be easily achieved. Two types of samples designed for broad bandwidth operation have been used in this experiment. In addition, unlike the past tuning experiments that suffer from serious ASE noise, this experiment demonstrates very high ASE suppression ratio (> 40 dB) over the entire tuning range by using a triangular ring cavity.
