Optical semiconductor device for laser light output
A recently granted patent (Publication Number: US12009636B2) discloses an optical semiconductor device designed to output a specific wavelength of laser light. The device includes a quantum well active layer situated between a p-type cladding layer and an n-type cladding layer, along with a separate confinement heterostructure layer and an electric-field-distribution-control layer composed of at least two semiconductor layers with higher band gap energy than the barrier layer in the quantum well active layer. This innovative device is fabricated on a GaAs substrate, ensuring efficient performance and reliability.
Moreover, the patent encompasses a semiconductor laser module incorporating the aforementioned optical semiconductor device. This module features a temperature-control module, an optical fiber for guiding the laser light, and an optical-coupling lens system for optical coupling. Additionally, the module may include an optical detector, an optical isolator, or an optical feedback unit to enhance functionality. Furthermore, the patent extends to optical fiber amplifiers utilizing the semiconductor laser module for amplification purposes, with variations in the amplification process such as Raman amplification. The use of a GaAs substrate in these devices ensures a robust and effective optical amplification system for various applications.
