摘要： A fiber-optic tunable filter and an intensity modulator respectively includes: a fiber having a polished surface and an evanescent-field; and a photonic crystal having plural cavities and a filler filled therein and attached to the polished surface, wherein the plural cavities and the filler decide a photonic band-gap of the photonic crystal and the photonic band-gap is adjusted to reflect a light with a specific wavelength through the evanescent interaction with the photonic crystal material. Based on the fiber side-polishing technique, all kinds of fiber active and passive devices are able to be manufactured easily, especially for a high speed intensity modulator using an EO (Electro-Optic) polymer as the filler.

摘要： An optical amplifier and a laser generator based on the fiber side-polished technology, having a high pumping efficiency, a low noise figure and a small footprint are provided in this application. The optical amplifier and the laser, which have a very long effective interaction length in conjunction with highly doped Erbium glass attached to its surface and an addition of a slanted fiber grating inscribed in the guiding core at the polished region can spatially separate the signal and pump power to simultaneously improve the pumping efficiency and optimize the penetrated depth of the signal evanescent-field. The spontaneous emission is kept from being amplified and therefore a high quality amplified signal is produced.

摘要： A method of manufacturing a compact fiber coupler. On a semiconductor substrate, a V-groove with a radius curvature R is formed. Then, a glue is positioned at both sides of the V-groove, and the glue is absorbed from both sides of the V-groove by capillarity. A first optical fiber and a second optical fiber are respectively fixed in the V-groove so that the cladding of the first optical fiber and the second optical fiber can be polished to form a first side-polished region and a second side-polished region. Thus, the compact fiber coupler is accomplished by aligning and fusing the first side-polished region and the second side-polished region together, in which a coupling region is formed between the first side-polished region and the second side-polished region.

摘要： A method for coupling a planar lightwave circuit and an optical fiber. A side-polished optical fiber is formed with a polished surface at its side. When the side-polished optical fiber and the planar lightwave circuit are coupled, the polished surface of the side-polished optical fiber is adhered to the planar lightwave circuit. According to an evanescent field interaction, signals transmitted in the planar lightwave circuit can be coupled to the side-polished optical fiber. Additionally, signals transmitted in the side-polished optical fiber can be coupled to the planar lightwave circuit.

摘要： A tunable optical fiber filter or reflector is composed of a single-mode optical fiber having UV-induced fiber gratings in its core region. A planar surface is formed by a mechanical polishing technique such that the planar surface is contiguous to the core region of the optical fiber. The planar surface is covered with a material having a refractive index close to the refractive index of the optical fiber. As the refractive index of the material is changed, the tuning of the reflection or transmission spectra of the optical fiber filter or reflector is attained. The tunable optical fiber filter or reflector is used in optical communication systems, sensoring systems, or as external cavities of lasers.

摘要： A method for preparing a fiber-optic polarizer involves a first step in which the cladding layer of a single-mode optical fiber is side-polished to form a planar surface contiguous to the core region of the single-mode optical fiber. The planar surface is formed thereon a buffer dielectric/metal composite thin film, or the planar surface is coated by sputtering with a metal layer which is then coated with a medium having a refractive index matching to that of the optical fiber. The polishing of the single-mode optical fiber is done by using a semiconductor substrate having one or more V-shaped recesses having a large curvature radius.
