The SAE AS5659 Wavelength Division Multiplexed (WDM) Local Area Network (LAN) standard defines network access (NAI) and backbone network (BNI) optical interfaces [1]. NAIs and BNIs provide optical connection to and within the backbone network, respectively. The backbone network is comprised of optical network elements (ONEs). ONEs include optical multiplex and optical transport layers. Client adaptation...
We describe techniques for phase-locked coherent optical communications, including wavelength synthesis for wavelength-division-multiplexed optical communications, compact coherent BPSK receivers, and coherent demodulation of WDM in the electrical domain. Index Terms - Coherent optical communications, phase-locked-loops, frequency synthesis, wavelength-division-multiplexing.
Recent advances in the field of photonic integration have made compact, small form factor, robust realizations of tunable transmitter arrays a reality. In this paper, we studied different chip architectures to best fulfill the requirements of avionic deployment. An optimal number of widely tunable transmitters to be integrated on a single chip is 4. Total power consumption presents a challenge, as...
