FAST SWITCHING ASYMMETRIC THERMO-OPTICAL DEVICE

摘要

The present invention refers to an asymmetric thermo-optical device comprising a waveguiding structure which comprises at least one input light path (1) and a first output light path (2) and a second output light path (3), the second output light path (3) having a smaller width than the first output light path (2), and the first output light path (2) being provided with a first heating element (4), characterised in that the second output light path (3) is provided with a second heating element (5). In a preferred embodiment of the invention the second heating element (5) is connected to a capacitor which is connected in parallel with the first heating element (4).
