EMCORE Releases High-Power, Ultra-Low RIN DWDM Laser Modules

ALBUQUERQUE, NM--(Marketwire - March 18, 2010) -  EMCORE Corporation (NASDAQ: EMKR), a leading provider of compound semiconductor-based components and subsystems for the broadband, fiber optic, satellite and terrestrial solar power markets, announced the introduction and immediate availability of a new line of high-power, > 100 milliwatt (mW), continuous-wave (CW) source laser modules for 1550-nm range DWDM applications.

The DWDM 100-mW high-power CW laser module, available in all ITU grid wavelengths, offers solutions for growing demands of high optical power in DWDM, CATV networks, and free space optics applications. The laser module is DC-coupled with a built-in TEC, thermistor, and monitor photodiode. The device is mounted in a 14-pin, OC-48 pinout compatible butterfly package with the optical isolator mounted on the TEC. It also incorporates an innovative, high efficiency coupling scheme to deliver more than 100-mW CW optical power at a low bias current. Features of these laser modules, model number 1782, include:

• Operating temperature ranges from -20°C to +65°C
• Ultra low RIN (relative intensity noise) is typically less than -170 dB/Hz
• Optical power output is greater than 100 mW
• Maximum laser bias current is 450 mA

"The ultra low RIN and high optical power makes this product family an excellent choice to design into externally modulated transmitters that require high optical power or dual optical power outputs for RFoG and FTTx networks," said Vu Tran, Optical Component Product Line Manager for EMCORE Broadband. The laser modules are immediately available. Please visit our booth at the Optical Fiber Communication Conference and Exposition (OFC) in San Diego on March 23-25, 2010, for more information.
