Other Related Research

Two ring diode lasers are optically coupled together to produce tunable, stable output through a Y-junction output coupler which may also be a laser diode or can be an active waveguide. These devices demonstrate a sharp peak in light output with an excellent side-mode-rejection ratio. The rings can also be made of passive or active waveguide material. With additional rings the device is a tunable optical multiplexer/demultiplexer. 11 figs.

Interferometric ring diode lasers

Journal Article - in OSTI.gov collection Hohimer, J.P. ; Vawter, G.A. ; Craft, D.C. ; Hadley, G.R.

We report the first demonstration of interferometric ring diode lasers. These devices show a sharply peaked light versus current curve with cw output powers up to 8 mW. The output emission is single-frequency with side-mode-rejection ratios up to 30 dB.

Optical logic using semiconductor ring lasers

Patent Application - in OSTI.gov collection Behfar-Rad, A.

This patent describes an optical logic element. It comprises a unitary, semiconductor ring laser having cavity legs, adjacent legs being joined at corresponding ends to form a closed path for light propagating in either a first or a second direction in the laser closed path; a facet at each juncture of adjacent legs, each the facet having a critical angle, the legs being joined at angles to cause propagating light to strike at least two of the facets at angles less than the critical angle, whereby the at least two facets are at least partially transmissive to light propagating inmore »« less

Unidirectional ring lasers

Patent Hohimer, J.P. ; Craft, D.C.

Unidirectional ring lasers formed by integrating nonreciprocal optical elements into the resonant ring cavity is disclosed. These optical elements either attenuate light traveling in a nonpreferred direction or amplify light traveling in a preferred direction. In one preferred embodiment the resonant cavity takes the form of a circle with an S-shaped crossover waveguide connected to two points on the interior of the cavity such that light traveling in a nonpreferred direction is diverted from the cavity into the crossover waveguide and reinjected out of the other end of the crossover waveguide into the cavity as light traveling in the preferredmore » direction. 21 figs.« less

Triggerable electro-optic amplitude modulator bias stabilizer for integrated optical devices

Patent Conder, A.D. ; Haigh, R.E. ; Hugenberg, K.F.

An improved Mach-Zehnder integrated optical electro-optic modulator is achieved by application and incorporation of a DC bias box containing a laser synchronized trigger circuit, a DC ramp and hold circuit, a modulator transfer function negative peak detector circuit, and an adjustable delay circuit. The DC bias box ramps the DC bias along the transfer function curve to any desired phase or point of operation at which point the RF modulation takes place. 7 figs.
