NON-POLARIZED MULTIWAVELENGTH LIGHT SOURCE

摘要

PROBLEM TO BE SOLVED: To provide a non-polarized multiwavelength light source wherein performance and efficiency are improved compared with a conventional multiwavelength light source. SOLUTION: The multiwavelength light source for outputting an optical signal having a plurality of channels is provided with an optical fiber amplifier having an I/O terminal for amplifying the optical signal inputted from the input terminal and outputting amplified spontaneous emission light to the input terminal; a reflector which is connected to the input terminal of the optical fiber amplifier for reflecting the outputted optical signal; and a comb filter arranged between the optical fiber amplifier and the reflector and having a passband for filtering the amplified spontaneous emission light for generating a multi-channel optical signal with a transmission spectrum of the amplified spontaneous emission light that has been filtered.
