The semiconductor device consists of a Fabry - Perot laser with deeply etched broadband distributed Bragg reflector mirrors. Single-mode operation is achieved by using feedback from an integrated filter. This filter contains an arrayed waveguide grating wavelength router and a semiconductor optical amplifier gate array. Design, simulation, and the first characterization results of this new integrated filtered-feedback tunable laser device are presented. It shows a combination of a simple and robust switching algorithm with good wavelength stability. A rate equation model predicts that a properly designed device can switch within 1 ns. The fast switching and reduced control complexity makes the device very promising for various advanced applications in optical telecommunication networks.Keywords: Advanced applications; Control complexity; Discretely tunable; Distributed bragg reflector mirrors; Fabry Perot lasers; Fast switching; Filtered feedback; Gate arrays; Integrated filter; Optical telecommunication networks; photonic integrated circuits; Ra Filtered feedback; packet switching; photonic integrated circuits; semiconductor lasers; tunable lasers201010.1109/JSTQE.2009.20380722016-02-24
