90° Hybrids

 90° Hybrids

The COH24 is a single polarization 90° optical hybrid that enables to extract phase and amplitude from a single polarization signal by performing four 90° phase stepped interferences between the signal and a Local Oscillator (LO).

The COH24-X is a new generation optical hybrid with improved performances (among other things, a wider operating wavelength range and much better dual uniformities).

The COH28 and COH28-X are based on two single polarization 90° optical hybrids that enable to extract phase, amplitude and polarization from a signal with any polarization. These products are purely passive and athermal. The COH24-X and COH28-X also feature a phase tunability option in order to perfectly adjust the 90° of the hybrid depending on the wavelength used.
