Abstract

The invention discloses an amplified spontaneous emission light source device, which comprises a circuit part and a light path part. Light emitted by a pump laser enters an erbium-doped fiber after passing through a wavelength division multiplexer to generate primary forward amplified spontaneously emitted light and backward amplified spontaneously emitted light. An A / D conversion circuit is connected with an output light power detection circuit, a current acquisition circuit and a temperature acquisition circuit. The pump laser is connected with an automatic temperature control circuit, a laser drive circuit, the temperature acquisition circuit and the current acquisition circuit. The laser drive circuit is connected with a D / A conversion circuit. A singlechip system is connected with the A / D conversion circuit, the D / A conversion circuit, a serial communication circuit, a liquid crystal display (LCD) circuit and a key scanning circuit. A power management circuit supplies power to each circuit. The amplified spontaneous emission light source device provided by the invention is convenient to use and high in working performance and output light power.

Description

Technical field [0001] The invention relates to a light source device, in particular to an amplified spontaneous radiation light source device. Background technique [0002] White light sources and tunable light sources have disadvantages such as high cost, low power, and low stability. Amplified Spontaneous Emission (ASE) light source is a broad-spectrum light source whose spectral range covers the C-band commonly used in optical communications. It is very suitable for the production and testing of optical fiber passive components and is widely used in dense wavelength bisection filtering. DWDM filter, coarse wavelength division multiplexing filter (CWDM filter) and other wavelength division devices and couplers, isolators, circulators, etc.; in addition, amplified spontaneous emission light sources are also widely used in the field of fiber grating sensing , Fiber optic gyroscope, and as the seed light source of dense wavelength division multiplexing system, etc. However, the...
