40 GHz-narrow band photoreceiver for clock recovery in 40 Gbit/s optical transmission systems

Narrowband photoreceiver for analog radio-over-fiber in the 24.25-29.5 GHZ band

“…In previous work, it was shown how resonant inductive peaking at the input of the TIA can boost the performance of conventional broadband transimpedance amplifiers for narrowband communication [5]. Similarly, dedicated narrowband photoreceivers [6][7][8][9][10] can be looked at to make optimal use of the narrowband nature of the future generation wireless bands. In such an approach, one can design the receiver to get an optimal power transfer from the photodetector to the load for a given frequency range instead of having suboptimal current-tovoltage conversion over a large band as is the case for broadband TIAs.…”
