Abstract: A fiber splicing apparatus of the present invention includes a support (120a, 120b) for supporting the two optical fibers (112a, 112b) such that the ends (114a, 114b) thereof are aligned and in physical contact, and a laser (130) emitting a laser beam (142) onto the ends of the optical fibers to heat and thereby fuse together the ends (114a, 114b) of the fibers (112a, 112b). According to another embodiment, an apparatus is provided for heating a region (115) of one or more optical fibers (112a, 112b). This apparatus includes a laser (130) emitting a laser beam (132) and an optical modulator (134) positioned to receive and selectively modulate the intensity of the laser beam (132) to project a modulated laser beam (138) along a first optical path that terminates at the end (114a, 114b) of the optical fiber(s) (112a, 112b) to be heated. This apparatus further includes a control loop (133) to monitor the intensity of the modulated laser beam (138) and control the optical modulator (134) to thereby regulate the intensity of the modulated laser beam (138) in response to the monitored intensity level.

Abstract: A fusion joint between a waveguide (1a) and an optical fiber (2) is created by irradiating the interface (4) between the optical fiber and the waveguide using a laser beam. The spatial distribution of the energy furnished to the interface presents a central zone of which the energy is reduced with respect to a peripheral zone, whereby to enable a relatively high energy laser to be used while avoiding bending of the waveguide. The laser beam is caused to irradiate a higher energy density upon the waveguide than the optical fiber, typically by offsetting the center of the laser beam towards the waveguide. The fusion is performed while a force F urges the waveguide and optical fiber towards one another, so as to avoid the creation of a void at the boundary. A supplementary polymer or mineral joint can be provided. A method for multi-fiber fusion pigtailing more than a single optical fiber to respective waveguiding regions in a planar waveguide includes using a diffractive optical element (130) to produce a multiple energy distribution.

Abstract: The mfr. is effected using a coloured product in a fluid state which is suitable to form the filter after hardening. The substrate is printed with a print head comprising a surface made of porous material (5) soaked with the coloured product. The print surface is textured (7-1, 8-1) in order to define the areas on which the coloured product is to be applied. The print head may be formed by mechanical abrasion or laser cutting to achieve the required design. The print substrate may be the final support for the filter, or alternatively an intermediate substrate may be used. The coloured product may be subject to a specific radiation - for example ultraviolet or infrared - in order to harden it.

Abstract: A method and structure for the mechanical and optical coupling of a plurality of individual planar optical devices (10, 20) to one another includes aligning the devices, bonding (35, 37, 38) the substrates (12, 22) of the planar devices (10, 20) to one another and subsequently fusing (40, 42, 44, 46) aligned optical waveguides (11, 29) utilizing a heat fusion technique. The substrates (12, 22) are bonded utilizing either heat fusion for a silica substrate or by a bonding adhesive for a silicon substrate. Once the aligned substrates (12, 22) have been mechanically bonded to one another, the optical pathways (11, 29) are coupled in one embodiment by heat fusion, preferably a focused CO2 laser (30) which completes the mechanical and optical interconnection of multiple devices. It is possible with such alignment, bonding, and fusion processes to couple numerous planar optical devices (10, 20, 50) in an array which can subsequently be packaged for use in relatively complex optical networks. The resultant devices display a high level of reliability, are relatively inexpensive to manufacture, and display excellent operating characteristics.
