Abstract:
A compression-tuned laser, comprising:a first optical waveguide, at least a portion of which having a transverse cross-section which is continuous and comprises a substantially homogeneous material, the at least portion of the first optical waveguide having an outer transverse dimension of at least 0.3 mm, the first optical waveguide including: an inner core disposed along the longitudinal axis of the first optical waveguide; and a first grating disposed within the core along the longitudinal axis, the grating reflecting a first reflection wavelength of light; a second optical waveguide including: an inner core disposed along the longitudinal axis of the second optical waveguide; and a second grating disposed within the core along the longitudinal axis; and an optical fiber including a gain material being optically disposed between the first and second optical waveguide; wherein at least the first optical waveguide is axially compressed to change the first reflection wavelength reflected by the first grating.
