M. Hamacher et al., 1ST HETERODYNE RECEIVER FRONTEND MODULE INCLUDING A POLARIZATION DIVERSITY RECEIVER OEIC ON INP, IEEE photonics technology letters, 7(2), 1995, pp. 179-181
For the first time a packaged polarization diversity coherent receiver
OEIC including detector units (photodetectors, JFET, load resistor) h
as been fabricated with the following data: waveguide loss 2 dB, 3 dB
balance within 0.4 dB, polarization extinction >30 dB (TM) and >17 dB
(TE), 3 dB cutoff frequency of 0.9 GHz, common mode rejection ratio 30
dB.
