See full text

The thermooptic modulator includes a wave guide (1) having a switching section (4), a refracting section (5) bordering the switching section (4) and extending transversely to a signal propagation direction (14) in the wave guide and a first heating element (8) extending on the refracting section (5) along a boundary (6) between the wave guide (1) and the refracting section (5). In order to improve signal suppression when the modulator is switched to an impermable state, a second heating element (9) is provided extending on the wave guide (1) along the boundary (6).
