Latest Patents

Yen's latest innovations include the "Laser Diode Module with a Built-In High-Frequency Modulation IC." This invention addresses the challenge of reflected noise that occurs during the reading of signals by a laser beam. By directly packaging this sophisticated technology within a metal cap, the high-frequency modulation integrated circuit (IC) connects through wire bonding with several legs, enhancing functionality. The design features four connection legs, where two serve as power terminals and the other two connect to an external automatic power control (APC) circuit. This innovation not only improves productivity but also reduces electromagnetic interference (EMI).

Additionally, Yen has developed a "Laser Diode Device with an APC Inside the Cap." This compact device, measuring no greater than 5.6 mm, incorporates an automatic power control circuit directly mounted in a heat sink within the metal cap. This design eliminates the need for an external circuit board, allowing for a more efficient voltage-driven operation instead of current-driven.
