ABSTRACT:
A semiconductor laser and optical waveguide are coupled together along a common optical axis and bounded at remote ends with reflective surfaces to form an optical resonant cavity. A periodic grating formed in a side surface of the optical waveguide directs some radiant energy out of the cavity in a direction not parallel with the common optical axis.
