摘要： An optical filter for filtering a spectral profile of an optical signal for providing an output signal having a desire gain profile, such as a flatten gain profile. The filter comprises an optical waveguide that includes a core disposed within a cladding having an outer dimension greater than 0.3 mm. A Bragg grating is imparted or written in the core of the waveguide that attenuates the received optical input signal in accordance with a defined reflection or transmission filter profile. The Bragg grating may be a slanted grating. The filter profile is complementary to the spectral gain profile of the input signal to provide an output signal having a substantially flat spectral profile of a desired wavelength band. The cladding of the waveguide may have a mechanically advantageous outer geometry (e.g., a “dogbone” shape) for allowing an axial compressive force to tune the Bragg grating. The waveguide may be package within an athermal device, which tunes the grating to compensate for temperature dependent changes. Further, the waveguide may be packaged in a tuning device to selective tune the gratings to shift the center wavelength of the spectral profile of the filter, or to change the shape of the filter profile.

摘要： A tunable external cavity semiconductor laser incorporating a tunable Bragg grating, including: a semiconductor gain medium; an elongated tuner housing having a tuner housing head and having a tuner housing foot, the tuner housing head and tuner housing foot being rigidly connected; a span of waveguide having a Bragg grating, for receiving the source light and for providing in turn the reflected light, and having a waveguide head and a waveguide foot, the waveguide head abutting the tuner housing head and the waveguide foot disposed toward the tuner housing foot; a piezoelectric crystal or other device or arrangement for providing a compressive force, disposed so as to abut the waveguide foot and also to abut the tuner housing foot, the means for applying a compressive force for exerting a compressive force on the span of waveguide along the direction of the axis of the span of waveguide, the compressive force being sufficient to alter the grating so as to affect the wavelength of light reflected by the grating. In some applications, the waveguide includes sections of different thicknesses, each having a sampled grating, the two sampled gratings being created so that at any given compressive force exerted by the piezoelectric crystal, the two gratings reflect at most one wavelength in common. The tunable laser in such an application therefore behaves as a stepped tunable laser.

摘要： A temperature compensated optical device includes a compression-tuned glass element 10 having a Bragg grating 12 therein, a compensating material spacer 26 and an end cap 28 all held within an outer shell 30. The element 10, end cap 28 and shell 30 are made of a material having a low coefficient of thermal expansion (CTE), e.g., silica, quartz, etc. and the spacer 26 is made of a material having a higher CTE, e.g., metal, Pyrex®, ceramic, etc. The material and length L5 of the spacer 26 is selected to offset the upward grating wavelength shift due to temperature. As temperature rises, the spacer 26 expands faster than the silica structure causing a compressive strain to be exerted on the element 10, which shifts the wavelength of the grating 12 down to balance the intrinsic temperature induces wavelength shift up. As a result, the grating 12 wavelength is substantially unchanged over a wide temperature range. The element 10 includes either an optical fiber having at least one Bragg grating 12 impressed therein encased within and fused to at least a portion of a glass capillary tube or a large diameter waveguide (or cane) with a grating 12 having a core 11 and a wide cladding, which does not buckle over a large range of compressive axial strains. The element may have a “dogbone” shape to amplify compressive strain on the grating 12. The device 8 may also be placed in an axially tunable system that allows the wavelength to be dynamically tuned while remaining athermal. In addition to a grating, the device may be an athermal laser, DFB laser, etc. Also, the entire device 8 may be all made of monolithic glass materials.

摘要： A tunable optical filter has a large diameter cane waveguide with “side-holes” in the cane cross-section that reduce the force required to compress the large diameter optical waveguide without overly compromising the buckling strength thereof. The large diameter optical waveguide has a cross-section of at least about 0.3 millimeters, including at least one inner core, a Bragg grating arranged therein, a cladding surrounding the inner core, and a structural configuration for providing a reduced bulk modulus of compressibility and maintaining the anti-buckling strength of the large diameter optical waveguide. The structural configuration reduces the cross-sectional area of the large diameter optical waveguide. These side holes reduce the amount of glass that needs to be compressed, but retains the large diameter.

摘要： A reconfigurable optical blocking filter deletes a desired optical channel(s) from an optical WDM input signal, and includes a spatial light modulator having a micro-mirror device with a two-dimensional array of micro-mirrors that tilt between first and second positions in a “digital” fashion in response to a control signal provided by a controller in accordance with a switching algorithm and an input command. A collimators, diffraction grating, and Fourier lens, collectively collimate, separate and focus the optical input channels onto the array of micro-mirrors. The optical channel is focused on the micro-mirrors onto a plurality of micro-mirrors of the micro-mirror device, which effectively pixelates the optical channels. To delete an input channel of the optical input signal, micro-mirrors associated with each desired input channel are tilted to reflect the desired input channel away from the return path.
