Emcore Corp. has developed a new line of high-power, >100mW, continuous-wave (CW) source laser modules for 1550nm range DWDM applications.

The DWDM 100mW 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 100mW CW optical power at a low bias current.

Features of these laser modules include less than -170dB/Hz ultralow relative intensity noise (RIN); greater than 100mW optical output power and 450mA maximum laser bias current. Operating temperature ranges from -20C to +65C.

"The ultralow 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.
