Lemon Photonics

Lemon Photonics Technology Co., Ltd. operates as a developer and manufacturer of semiconductor laser chips, application modules, and optical engine solutions. Founded in 2018 by Dr. Xiao Yan in Shenzhen, China, the company has established itself within the application-specific semiconductor industry. Dr. Xiao Yan, who serves as CEO, brings extensive experience to the firm, holding a B.S. in Precision Instrumentation and an M.S. in Optical Engineering from Tsinghua University, as well as a Ph.D. in Electronics and Computing from the University of Illinois, with nearly two decades of R&D experience in the laser and optoelectronics sector.

The company's business model is centered on the research, development, and sale of high-end semiconductor electro-optical devices. It vertically integrates the processing and manufacturing of semiconductor lasers, extending its technologies to various application areas. The client base is diverse, spanning industries such as mobile robotics, high-end industrial processing, smart cars, 3D sensing, laser medical beauty, and security monitoring. By providing application services and collaborating strategically with key customers in these fields, Lemon Photonics generates revenue through the sale of its specialized products. The firm operates with a hybrid fab model, which supports asset-light operations and full-process control, and maintains a significant production capacity with a reported monthly output of over 4,000 6-inch wafers from three globally certified production lines.

Lemon Photonics' core product portfolio is built around three main laser technologies: Vertical-Cavity Surface-Emitting Lasers (VCSEL), Horizontal-Cavity Surface-Emitting Lasers (HCSEL), and Edge-Emitting Lasers (EEL). Its VCSEL chips are utilized in 3D sensing, gesture recognition, and medical applications. The HCSEL products are designed for high beam quality in 3D sensing applications, while the EELs offer high power and reliability for laser pumping, industrial processing, and LiDAR. The company also produces laser modules and engines, such as the HCSEL line laser projection module, which enhances the signal-to-noise ratio for radar systems, machine vision, and industrial processing. A significant milestone was achieved in 2021 with the shipment of millions of VCSEL chips.
