About This Product

■Summary

We custom manufacture quantum dot lasers, which have excellent temperature characteristics and resistance to reflected light and are ideal as light sources for optical communications and silicon photonics, as well as epiwafers, gain chips, TO-CAN packages, etc. according to customer requests.・We are selling it. We provide consistent support from prototyping to mass production.

■Up to epitaxial growth

・Providing form: Epiwafer ・High quality epitaxial growth on 3 inch or 4 inch GaAs substrates. ・Growable layers: InAs quantum dots, InGaAs quantum wells, GaAs, AlGaAs

■ Diffraction grating embedding until regrowth

・Provided form: Epi wafer with diffraction grating ・Active layer epitome, diffraction grating formation and buried regrowth.

■Up to wafer process

・Provided form: Wafer after processing ・Epigraphy, CAD work, mask production, and wafer processing.

■Up to bar processing or chip processing

・Provided form: bar or chips ・We perform epitaxial, wafer process, bar formation, end surface coating, and chip formation.

■Up to TO-CAN packaging

・Provided form: 5.6mm TO-CAN package ・After epitaxial, wafer process, and chip processing, the laser chip is packaged into a 5.6mm TO-CAN.

■Application example

・Light source for optical communication ・Light source for silicon photonics (data center communications, supercomputers, LiDAR, in-vehicle communications, mobile phone base station communications) ・​Underground resource exploration (high temperature 175 - 200 degrees)
