Microwave monolithic phase shifter for optical transmission at 40 Gb/s
05 February 2004
This paper deals with a design technique for an integrated planar phase shifter on GaAs substrate at millimetre-wave frequencies for optical transmission applications at 40 Gb/s. We numerically show how an amplifier can be adequately associated with a nonconstant magnitude phase shifter to avoid a magnitude modulation of the optical signal when tuning the phase shift.
