1. Wavelength tunable external cavity laser comprises:

  • Semiconductor laser diode, this semiconductor laser diode is exported multiple wavelength optical signal and is installed on first substrate;

    AndThe wavelength-tunable reflective filter, this wavelength-tunable reflective filter is installed on second substrate, utilization is at semiconductor laser diode and have the resonance of the exocoel that forms between the Bragg grating of predetermined period, export the single wavelength light signal in the described multiple wavelength optical signal, and regulate the wavelength of single wavelength light signal of being exported by the refractive index that changes Bragg grating.
