英文摘要	a free-space 2 x 4 90 degrees optical hybrid with electro-optic modulation is presented. the hybrid principally consists of two pairs of electro-optic crystal plates coated with gold electrodes and a polarization analyzer. the optical hybrid uses the birefringence effect of a crystal to split and combine a signal beam and a local oscillator beam, uses the electro-optic effect to introduce a phase modulation and produce a phase shift, and outputs four-channel signal/local oscillator mixed beams whose phase difference can be adjusted continuously. a linbo3 crystal is used to design and manufacture the space optical hybrid, and an experimental system is used to verify its performance. the results show that the output phase of the hybrid is continuously adjustable, enabling the hybrid to function perfectly as a 2 x 4 90 degrees space optical hybrid under an appropriate electric field, and that the phase error can be compensated for by an electric field adjustment.
