NeoPhotonics shrinks narrow-linewidth laser, ICR for 100G coherent optical transport

NeoPhotonics Corp. (NYSE: NPTN) has used European Conference on Optical Communications (ECOC) in London, to introduce small-form-factor versions of their narrow-linewidth tunable laser (NLW-TL) and intradyne coherent receiver (ICR) for coherent transmission applications. The company says the new devices not only will meet 100-Gbps requirements, but 200G and 400G applications using higher-order modulation schemes such as 16QAM as well.

The first of the new products is a narrow-linewidth, micro-integrable tunable laser assembly (micro-ITLA), which offers a factor of three footprint reduction versus the previous generation of ITLAs. The second new offering is a small form factor ICR, which NeoPhotonics says is half the size of current ICRs. The SFF-ICR has the option of an integrated VOA on the signal path and a monitor photodiode (MPD) to simplify board level integration. The device is applicable to both single incoming channel and multiple incoming channel applications.

The reduced size of the devices makes them applicable to the upcoming generation of pluggable coherent transceivers.

“Photonic Integration has played a major role in enabling the current generation of coherent systems which are currently transforming the optical communications landscape and we are proud of the contribution NeoPhotonics has made to this sea change,” said Tim Jenks, chairman and CEO of NeoPhotonics. “As exemplified by these new products, we are utilizing our photonic integration technology to bring our customers the benefits of reduced size, reduced power consumption, and higher levels of integration and performance.
