KYOCERA SLD Laser demos high-speed underwater wireless optical communication and custom GaN laser capabilities
In booth 1667 (Hall C) at SPIE Photonics West 2024 (30 January–1 February), KYOCERA SLD Laser Inc (KSLD) of Goleta, near Santa Barbara, CA, USA — which is commercializing gallium nitride (GaN)-based laser light sources for automotive, mobility, specialty lighting and consumer applications — is demonstrating new LaserLight technologies including a high-speed, bidirectional link for underwater wireless optical communication (UWOC) and custom-chip GaN laser capabilities.
Also, at 5:20pm PST on 31 January in room 2024 (Level 2 West), R&D process engineering manager Dr Phillip Skahan is presenting ‘Advances in InGaN Laser Diodes for Emerging Applications in the Visible Spectral Range’
The high-speed, bidirectional link being demonstrated is powered by KSLD’s GaN-based blue laser to enable UWOC. Laser LiFi is being adopted in various applications including undersea and space, secure office, factories, defense and security, as well as future smart cities. Recognized with the 2023 Prism Award, KSLD’s LaserLight LiFi system offers white and IR illumination with 1Gbps transmission rate bi-directionally in air to support the future of wireless connectivity. The new blue laser powered technology expands this system capability into underwater applications.
Based on the firm’s GaN epitaxial growth, epitaxial layer transfer and wafer-level facet formation technologies, KSLD’s custom-chip laser capabilities are being introduced to the market for customers needing specialized GaN-device-based products. During the exhibition, a selection of GaN laser products is being shown in KSLD’s booth, including customized single-mode and multi-mode lasers at a variety of visible wavelengths. These new devices can enable advances in applications including quantum sensing, quantum computing, directed energy, 3D printing, optical wireless communication, biomedical, and life sciences.
KSLD is showcasing the LaserLight-module-based automotive headlight assembly that offers high-brightness white and infrared (IR) dual illumination for night vision and sensing. The headlight assembly provides full features of low beam and high beam enabled by compact size modules. The ultra-compact LaserLight modules have a slim profile with less than a 12.7mm lens height, enabling flexibility for designers.
In Skahan’s talk, KSLD is presenting the latest performance of efficient, high-power lasers spanning the violet-to-green wavelength range as well as novel applications for its unique transfer technology. In addition, Skahan is providing updates on ultra-short-cavity in-plane laser diodes and other technologies for specialty chip applications.
KYOCERA SLD Laser is hosting meetings in person at Photonics West in booth 1667 and virtually by appointment.
