Problem
Many applications require specialized vertical-cavity surface-emitting lasers (VCSELs) and photodiodes with specific performance characteristics, but sourcing custom-designed and tested components can be challenging and time-consuming. Off-the-shelf solutions often fail to meet the stringent requirements of advanced sensing, communication, and industrial applications.
Solution
Dallas Quantum Devices (DQD) provides custom photonic solutions, specializing in the design, fabrication, and testing of VCSELs and photodiodes tailored to demanding applications. DQD leverages a network of manufacturing partners and in-house testing capabilities to deliver known good die and packaged components with characterized performance. Their services encompass III-V epitaxial material growth, device fabrication, custom optical design, and assembly, enabling them to create solutions optimized for specific wavelengths, power levels, and modulation requirements. DQD's expertise covers a range of VCSEL types, including single-mode polarization-locked, high-speed, and high-power devices, as well as custom photodiode designs.
Target Audience
DQD serves customers in data communications, in-flight communications, laser illumination and ranging, magnetometers & atomic clocks, automotive infotainment & LIDAR, and medical industries requiring custom VCSEL and photodiode solutions.
