1550nm LiNbO3 2.5Gb/s Intensity Modulator

1550nm LiNbO3 2.5Gb/s Intensity Modulator

Idealphotonics' lithium niobate (LiNbO3) intensity modulator is made of titanium diffusion or proton exchange process. The Mach-Zehnder type optical waveguide, the input and output optical fiber and the waveguide are precisely obliquely coupled, and the electro-optical effect of lithium niobate material is used to achieve intensity modulation of optical signals.

Product features：X-cut Y-transmitted lithium niobate、 Titanium diffused or proton exchange waveguide、 Low driving voltage、 Independent bias electrode · Zero chirp、 Precise oblique coupling between fiber and chip, greatly reducing、 Backlight reflection、 Excellent long-term stability

Part Number：--

Application area：Pulse generation, pulse shaping, pulse picking、 Carrier suppression、 Fiber optic sensing system、 Pulse application、 Analog transmission、 LiDAR
