SLED with Drivers

SLED with Drivers

A superluminescent diode (SLED or SLD) is an edge-emitting semiconductor light source based on superluminescence.
It combines the high power and brightness of laser diodes with the low coherence of conventional light-emitting diodes.

DenseLight has a comprehensive portfolio of SLEDs. It covers wavelength from 1250 nm to 1700 nm, power from 0.2mW to 50mW and spectral width from 25nm to 100nm.

 

The DL-BX9/BX10 series consists of a built-in current driver, a temperature controller and a DenseLight standard 14 pin butterfly package DL-CSxxxxA.

Similarly, the DL-BZ1 series consists of a temperature controller, a DenseLight standard 14-pin butterfly package CL-CSxxxxA and a built-in current driver capable for CW driving, digital or analog modulation input.

 

Select the SLED module in place of CSXXXXA from the following:

  • DL-BX9-CSXXXXA
  • DL-BX10-CSXXXXA
  • DL-BZ1-CSXXXXA
