Title: Mode coupling in hybrid square-rectangular lasers for single mode operation

Abstract

Mode coupling between a square microcavity and a Fabry-Pérot (FP) cavity is proposed and demonstrated for realizing single mode lasers. The modulations of the mode Q factor as simulation results are observed and single mode operation is obtained with a side mode suppression ratio of 46 dB and a single mode fiber coupling loss of 3.2 dB for an AlGaInAs/InP hybrid laser as a 300-μm-length and 1.5-μm-wide FP cavity connected to a vertex of a 10-μm-side square microcavity. Furthermore, tunable single mode operation is demonstrated with a continuous wavelength tuning range over 10 nm. The simple hybrid structure may shed light on practical applications of whispering-gallery mode microcavities in large-scale photonic integrated circuits and optical communication and interconnection.

  • We report the observation of anomalous polarization coupling effects occurring in injection-locked transversely excited atmospheric (TEA) CO/sub 2/ lasers, deduced from studies of the injection detuning parameter under varying conditions of polarization and injection power. For the special case of injection with orthogonally polarized radiation we have determined the existence of an optimum operation point, exhibiting minimum sensitivity of single mode operation to the detuning parameter. Off-resonance injection locking of untuned TEA cavities is also discussed.
  • A new AlGaAs phased array laser structure with dummy stripes outside the stripe region is developed. The dummy stripes are dashed line stripes along both edge elements of the array stripes. Therefore, current in these dummy stripes does not cause lasing, but does increase the temperature of the edge elements. Thermal distribution in the array stripes, which mainly causes multimode oscillation in phased array lasers, is effectively unified by the dummy stripes. As a result, completely single lateral 180{degree} mode continuous-wave operation is realized for the first time in this novel phased array laser.
  • A buried heterostructure broad area quantum well heterostructure Al/sub x/Ga/sub 1-//sub x/As-GaAs laser diode modified with a small multiple stripe pattern near its center is described that operates single mode and narrow lobe (<2 /sup 0/) from threshold (I/sub th/) to 2I/sub th/ or 3I/sub th/. The broad area (wide stripe) buried heterostructure laser is made by impurity-induced layer disordering.
  • We have achieved single-mode operation in a pulsed hybrid optically pumped D{sub 2}O far-infrared laser. The active volume of the resonator was divided into two sections separated by a thin plastic foil. The larger section served as the main gain medium and the shorter section as the mode selective element. The vapor pressure in the smaller volume was either very low or alternatively about three times higher than the pressure in the main part. In both cases single-mode operation was achieved without any reduction of the total output energy.
