We report the design and experimental results of a widely tunable three-section laser by using reflecting Fabry–Perot filters with deeply etched lossy half-wave coupling trenches. Good performance in side-mode suppression ratio and wavelength tuning range has been demonstrated experimentally. By introducing moderate coupling loss in the half-wave coupling… CONTINUE READING
