Oclaro’s (Denville, NJ) HL63142DG high power red laser diode offers an inbuilt monitor photodiode at a lasing wavelength of 637nm. It is a unique design which enables system designers to control optical power output by monitoring the photodiode current and adjusting power variants and temperature for precise control and constant performance.

This laser diode operates at a temperature range up to 50°C at 100mW in the 637nm visible wavelength band in a TO industry standard 5.6mm package with N type pin configuration. It offers low operating current and low operating voltage which maintains low energy consumption, even at 100mW high output power with TE mode oscillation and single transverse mode.

Oclaro (Opnext) has also introduced another new high-power red laser diode with built-in monitor photodiode. The HL65051DG 660nm laser diode is designed for applications such as LIDAR (laser imaging detection and ranging) and plastic optical fibre (POF) communications. The HL65051DG operates at a temperature range of up to 60°C and delivers 120mW in the 660nm wavelength band in a 5.6 mm diameter TO industry standard package.
