LD-450-1600MG PDF Datasheet – Blue Laser Diode

A laser diode is a semiconductor device that emits coherent light through a process called stimulated emission. It’s a type of diode that is designed to produce a highly concentrated, narrow beam of light. Laser diodes are commonly used in a wide range of applications, including telecommunications, laser pointers, barcode readers, laser printers, medical equipment, and more.

LD-450-1600MG is a blue multi transverse mode laser diode emitting at typically 450nm with rated output power of 1600 mW CW, in a standard 5.6 mm TO package.

1. Blue Laser Diode: A blue laser diode is a type of laser diode that emits light in the blue part of the electromagnetic spectrum. Blue laser diodes typically emit light with wavelengths around 405 nanometers (nm), 445 nm, or 473 nm. These shorter wavelengths are challenging to produce using traditional semiconductor materials, which is why blue laser diodes are a significant technological achievement. Blue laser diodes are used in various applications such as high-density optical storage (e.g., Blu-ray), medical equipment, scientific research, and laser displays.

E2505H19 – 2.5 Gbits/s Moudlated Isolated Laser Module

Part Number: E2505H19

Function: E2500-Type 2.5 Gbits/s Electroabsorption Moudlated Isolated Laser Module (EM-ILM)

Package: Module type

Manufacturer: Agere Systems


E2505H19 datasheet pdf


The E2500-Type EM-ILM is a 1.5 µm laser with an integrated electroabsorptive modulator packaged in
an industry-standard, 14-pin butterfly package. The device has been designed to be used in 2.5 Gbits/s
extended-reach applications where the distances between regenerators is in the range of 150 km – 1000 km. To boost the transmitter power high enough to reach the receiver, the device typically is coupled with an erbium-doped fiber amplifier (EDFA) such as Agere Systems Inc.’s 1724 EDFA. The standard product is specified for use up to 360 km (E2505 Series) and 600 km (E2502 Series).



1. Integrated electroabsorptive modulator
2. 1.5 µm wavelength
3. Characterized for 2.5 Gbits/s operation
4. Very low dispersion penalty over 600 km
5. Low modulation voltage
6. Temperature stabilized
7. Wavelengths selectable to ITU-T standards
