EMCORE releases ultra-low RIN DWDM laser modules

MARCH 21, 2010 -- EMCORE Corp. has announced the introduction and immediate availability of a new line of >100 mW, continuous-wave (CW) source laser modules for 1550-nm range DWDM applications.

MARCH 21, 2010 -- EMCORE Corp. (NASDAQ: EMKR) has announced the introduction and immediate availability of a new line of >100 mW, continuous-wave (CW) source laser modules for 1550-nm range DWDM applications.

The DWDM 100-mW high-power CW laser module, model number 1782, available in all ITU grid wavelengths, is designed to offer 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 a high efficiency coupling scheme to deliver more than 100-mW CW optical power at a low bias current.

Features of the 1782 laser modules include:

  • operating temperature ranges from -20°C to +65°C
  • relative intensity noise (RIN) 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.
