Abstract
The first demonstration of a high sidelobe suppression, tunable, electro-optic filter fabricated in lithium niobate for 1.55 μm is reported. Weighting of the mode convenor structure using a Taylor distribution resulted in a −3 dB passband width of 1.6 nm and nearest sidelobes of −25 dB. A continuous, linear electro-optic tuning rate of ±30 V/nm is also reported.Keywords
