“…It was shown that with this approach, the frequency drift due to temperature changes can be reduced from 7 GHz to less than 1 GHz. In another publication by Fürst et al [6], a ring resonator laser was forced to operate in a single-laser mode by using filtered feedback from a tunable narrow-band DBR grating. In their paper, the authors report a switching speed of 450 ps.…”

Abstract-A novel discretely tunable laser based on filtered feedback is presented. The semiconductor device consists of a FabryPerot 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.

It has been successfully investigated for the rst time that strength of optical injection locking also depends on the size of semiconductor ring laser. Theoretical study for frequency response of optical injection locking semiconductor ring laser in the master slave conguration using direct, amplitude and phase modulation of master laser is discussed. In the unidirectional regime the locking range of semiconductor ring laser becomes wider when semiconductor ring laser with smaller size is used. Simulation results predict an incredible enhancement in the modulation bandwidth (> 500 GHz) of the slave semiconductor ring laser when used with smaller laser cavity length (50 µm) in the stable unidirectional regime.

A modified ring laser geometry is presented to promote stable unidirectional lasing. The effects of directional coupling and facet reflectivities are investigated with respect to quantum efficiency, directionality, and side-mode suppression ratio of the lasing spectra. Simulation and experimental results are presented showing single mode ͑Ͼ20 dB side-mode suppression ratio͒, unidirectional lasing on an InP based multiple quantum well material.
