Broadband Source System using several multi-wavelength superluminescent diode chips and 1×N optical fiber coupler

摘要

invention multiple multi-wavelength high-intensity light-emitting device (SLD) chip of 1 N optical fiber coupler for use relates to a broadband light source system, realized by wavelength multiplexed. According to ; the invention, the difference of each of the center wavelength of the spectrum line width I 1, 2, ..., N ( 2 = 1 + , ..., N = N-1 + ) of N two multi-wavelength high-brightness light-emitting device (SLD) and chips; And high-brightness light-emitting device (SLD) a driver for driving them; N number of multi-wavelength high-intensity light-emitting device (SLD) 1 N fiber optic coupler for combining the light emitted from the chips; A portion of the light outputted therefrom as an optical fiber coupler that separates a portion of the light to use in the feedback control; And monitoring PD for monitoring the separation of light fraction; According to the monitored characteristic of light high-intensity light-emitting device (SLD) broadband light source system, characterized in that made in a power controller for controlling the power of the driver feedback is provided.
