Casela Technologies introduced its 1310nm band high-power, continuous-wave (CW) distributed feedback (DFB) lasers .
Casela’s new 1 and 2 mm long DFB lasers achieve 125mW to 200mW optical power when uncooled and 300 to 400mW, respectively, when cooled, enabling the use of single laser for DR4 and DR8 transceivers. High optical powers are achieved at industry-leading power conversion efficiencies of 30% when cooled and 20% when uncooled operating at the maximum rated power. Key features include large modes with near-circular profiles that improve coupling efficiency to fibers or silicon-based waveguides and reliable operation proven during accelerated life testing. The same high-efficiency, high-power laser design is also available at other WDM, LAN-WDM and CWDM4 wavelengths.
“Casela was founded by industry veterans to focus on an innovative path to higher laser powers and efficiency demanded by new requirements in datacenters and system-on-chip (SOC) applications,” said Dr. Bo Lu, CEO of Casela Technologies. “With the demonstration and publication of our industry-leading laser results at OFC 2023, we are announcing our new laser platform and products for transceiver and co-packaged optics applications. We are also pleased that Casela’s high-output laser performance has been validated by multiple customers and will be available in high-volume production in 2H2023.”
