Notes:
Total and partial reflection are demonstrated at the bends of V-shaped lasers. By varying the angle of incidence to the facet at the bend, the reflectivity at this facet can be changed. Two totally and one partially reflecting V-shaped lasers are combined in a unibodied structure to realize a triangular-shaped ring laser (trilaser). Trilasers are made of three sections which meet at three facets. Two of the facets provide total internal reflection while the third allows partial transmission from which light output is obtained. The Q of the resultant planar cavity is modified by geometry, without the need for facet coating. V-shaped lasers and trilasers are formed by using the chemically assisted ion beam etching technique in an AlGaAs/GaAs-based single quantum well graded-index separate confinement heterostructure material.
