Abstract: A thermally tunable optical fiber device, such as a fiber grating, comprises a length of optical fiber (10) and a heater (23) including an unslotted microcapillary tube (23A) that surrounds the optical fiber (10). The microcapillary tube is made of an electrically resistive material and forms the heater (23) itself. The heater may further comprising a plurality of nested tubes (23B, 33B, 43B), wherein each nested tube includes thin film heating elements.

Abstract: In accordance with the invention, a modulated RZ pulse source comprises a modulated light source optically coupled to a stabilized Bragg grating filter and one or more optical taps. The light source is preferably modulated in power and frequency and has an adjustable channel wavelength λ. The Bragg grating filter has a reflectivity bandwidth having a high slope reflectivity cutoff and is preferably tunable. A feedback arrangement responsive to the taps keeps the source channel wavelength λ on the edge of the reflectivity bandwidth for shaping RZ pulses. When the Bragg grating is stabilized, the feedback system maintains λ at a value linked to the grating reflectivity edge and, by overlapping at least part of the optical spectrum of the source, converts the modulated source light into RZ pulses with high extinction ratio (≥ 12 dB). The result is a high power, jitter-free RZ pulse source that is compact, inexpensive and power efficient.

Abstract: The present invention is predicated on applicants' discovery that an appropriately spaced and dimensioned internal gap cladding can substantially reduce short wavelength cladding mode loss in a fiber Bragg grating. A fiber Bragg grating is provided with a ring of closely spaced, longitudinally extending gap regions (30) in the glass peripherally surrounding the core (10). The gaps are spaced apart by thin glass webs (31) having a thickness less than a wavelength of the light being transmitted and are disposed peripherally about the core at a distance of 2-10 wavelengths from the core center. The thin webs limit the passage of the light between the gaps. The combination of webs and gaps acts as an internal thin cladding which supports fewer cladding modes than conventional glass cladding and, significantly, provides increased wavelength spacing between the Bragg resonance and the first cladding mode resonance.
