Beat length measurement in directional couplers by thermo-optic modulation
In integrated optical directional couplers formed by two parallel waveguides, we measure the difference Δβ = β<sub>even </sub>- β<sub>odd</sub> between the propagation constants of the 'supermodes'. They are coupled locally by heating a fine spot on one of the guide...
