Abstract
Provided is a tunable external cavity laser. The tunable external cavity laser includes that a bragg grating hermetically packaged in a TO can, a superluminescent diode (SLD) using an optical source signal and an optical fiber. A lasing wavelength is decided when the optical source signal emitted from the SLD is reflected by the bragg grating and the lasing wavelength is output to the optical fiber through the SLD.
