The 3 GHz bias-free intensity modulator is housed in a compact package. The bias point of the Mach Zehnder Interferometer (MZI) is set to operate at the half-intensity point (quadrature). Due to this unique design, a complicated bias control circuit is not required. The modulator provides superior signal quality over a wide range of wavelength in the C and L-bands. This modulator can be used to modulate unpolarized light source such as: tunable lasers and ASE sources. These devices have a bandwidth of >3 GHz that can be used for both analog modulation, optical pulse generation, and digital data modulation. This device is built with proton exchange waveguide, so it contains a built in polarizer.
