Laser Narrow Linewidth DFB

NeoPhotonics’ Narrow Linewidth Distributed Feedback Lasers (NLW-DFB) are designed to provide low-noise, single mode 1550nm laser source for cost effective telecom and sensing application. In telecom, NLW-DFB lasers enable fixed wavelength coherent applications where as in 3D sensing/Lidar applications, due to its narrow linewidth, NLW-DFBs deliver +200m range. NeoPhotonics’ NLW-DFB laser array technology when used along silicon photonics can enable chip scale, compact photonic integrated circuits for telecom and 3D sensing applications.

NLW-DFB lasers are manufactured in NeoPhotonics’ in-house fabs. Lasers are qualified to GR-468 requirements and widely deployed since early 2000s.
Laser design is a buried hetero-structure with optimized quantum well to provide high optical output power and narrow linewidth. These lasers temperature and current tuned to achieve desired operating frequency with typical output powers > 16dBm. Temperature tuning enables optical frequency tuning of ~400GHz whereas laser current tuning provide ~0.1GHz/mA optical frequency tuning

Semiconductor Optical Amplifier (SOA)

NeoPhotonics’ family of high power, single-mode semiconductor optical amplifiers are designed to provide high saturated output power for telecom and 3D sensing applications. These SOAs have several advantages. Since they are ultimately just semiconductor chips, SOAs are much more compact than EDFAs: around a millimeter in size, which makes them a lot easier to package with a photonic chip into a module or transceiver. SOAs are also both lower cost and are very efficient at converting current into light, which is essential for meeting a strict power consumption budget.
With a buried heterostructure and multi-quantum well structure active core, NeoPhotoncis SOAs provide typical saturated output power in excess of 250mW in the 1550nm wavelength range. High power SOAs are manufactured in NeoPhotonics’ in-house fabs and are design to be GR-468 compliant.
