Abstract :
A new heterodyne receiver is demonstrated. The local laser diode (LD) was built-in and no fibre was used between the parts. The number of optical parts and assembly processes was reduced, and a better performance was achieved because there was no polarisation fluctuation of the local light. The effect of a mismatch in the beam profile is discussed.
