    Article: Theoretical Analysis of a New Technique for Inertial Rotation Sensing Using a Semiconductor Ring Laser
    A. Perez-Serrano, A. Scire
    [show abstract] [hide abstract]
    ABSTRACT: We introduce a new technique for the measurement of inertial rotations using a semiconductor ring laser. Inertial rotation introduces a frequency deviation of the optical frequency of the two counterpropagating waves in the laser cavity, whereas mode coupling causes frequency attraction (frequency pushing) and finally locking at low rotation rates, washing out the small Sagnac frequency difference to be measured. Here we propose to measure inertial rotation whitin the so-called locking band using the phase/amplitude dependence on detuning found for the oscillating modes under the gain line. The dephasing accumulated by the two counterpropagating waves unbalances the fields' amplitudes within the locking region. We analytically derive the responsivity function quantifying the two-mode power unbalance versus rotation rate, by means of a two-mode rate equations model. Noise performance of a possible rotations sensor are also discussed by calculating the noise equivalent rotation rate.

    ABSTRACT: In recent years semiconductor ring lasers (SRLs) have attracted interest for their diverse potential application, e.g. their fast directional bistability recently opened up a new scenario for the development of all- optical memories and signal processing. Besides, SRLs show unexpected dynamical behaviors, such as hysteresis in the lasing direction, and peculiar lasing mode selection rules. In this contribution, we present an experimental and theoretical investigation concerning the modal structure and selection rules of a SRL with output waveguides.

    ABSTRACT: 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 (>20 dB side-mode suppression ratio), unidirectional lasing on an InP based multiple quantum well material.
