About Us

Established in 2012, LD-PD has become one of the leading providers in photodetectors, laser diodes and some related driven products.Our R&D team are well-educated, well-trained and dedicated to solving the most common problems in today's optoelectronic technology. We adopt the most innovative fiber optic products and various high-end instruments to develop products that better meet market needs. Our core competiveness is our high power, high reliable laser diodes. What's more, LD-PD has been a manufacturer of Si materi detector and high speed Germanium transistors and diodes since 2018 and a manufacturer of infrared photodetectors since 2016. We offer SI,Ge, p-n, APD and InGaAs p-i-n high speed and large area photodetectors for radiation detection and telecommunication applications. LD-PD boasts an inspection system in accordance with MIL-I-45208. Our Laser diode and Photodiodes are subjected to Telcordia testing requirements (TA-NWT-00093) and MIL-STD-883 test methods.

These lasers 

LD-PD INC provides laser diode epitaxy over a wide wavelength range in GaAs and InP based materials. We are a III-V base semiconductor processing lab Wavelengths:

400nm-2400nm

InAlGaAs/InGaAs”

We are also able to customize the epitaxy for any other specific wavelength required.

In the process of innovation, LD-PD'S laser engineers have amassed a high level of technical expertise and created an array of tools to meet customers’ requirements in laser chips. Our design engineers utilize state-of-the-art physical laser modeling software and waveguide design tools to ensure the function of the laser chips is fully considered. Our Diode Laser products include multimode single emitters and multi-emitter fiber coupled modules, single mode laser diodes, laser diode bars and stacks, and VCSELS, SLD. And We also offer a wide selection of UV laser diodes, blue laser diodes, red laser diodes, and IR laser diodes. The output power ranges from mWs on the single mode laser diodes, to watts in the multimode single emitters and VCSELS. We are really your best partner in laser diodes and Photodiodes.
