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:



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.
