Abstract
We have fabricated and tested coupled integrated coupled and branching waveguide lasers in Nd glass substrates1 . By making two or more parallel diffused channel or ridge waveguides close together on rare-earth doped glass substrates as shown in Fig's 1 , a set of coupled waveguide lasers can be fabricated which produce two closely spaced light waves, the symmetric and anti symmetric modes of the structure. The difference between their frequencies is in the microwave regime. Such devices can serve as single-sideband optical carrier sources. We have fabricated both diffused channel waveguides as shown in Fig. 1 a and ridge waveguides as shown in Fig. lb. The ridge waveguides can be bend through smaller radii than diffused wave guides for the same loss of light.
