1. A coherent optical receiver, comprising:
an integrated coherent receiver (ICR) configured to coherently detect a first optical frequency sub-band of a multiple-band optical source;
a local oscillator (LO) in operable communication with the ICR, and having an LO center frequency; and
a processor including (i) an analog-to-digital converter (ADC) configured to convert the detected first optical frequency sub-band into a first received digital signal, (ii) a signal recovery unit configured to recover a first data stream from the first received digital signal, (iii) a decoding unit configured to decode the recovered first data stream and output a first processed data signal corresponding to the first optical frequency sub-band,
wherein the ICR is further configured to coherently detect K sub-bands of the multiple-band optical source, K being an integer greater than or equal to 1,
wherein the multiple-band optical source has a first receiver bandwidth, and
wherein the receiver is configured with a second receiver bandwidth less than the first receiver bandwidth.
