    摘要: A resonator for the modal control of a laser with a gain medium having a non-circular cross-section in a plane perpendicular to the optical axis of the resonator. It has a graded reflectivity mirror as the output coupler. The graded reflectivity mirror consists of a partial reflector which has a reflectivity that varies gradually according to the position on the mirror's surface. The resonator is either astigmatic or the graded reflectivity mirror has a non circularly symmetric reflectivity profile or both. It allows the production of a good optical quality beam with an efficient energy extraction.

    摘要: An athermally packaged optical fiber device, such as a Bragg grating, is provided. The device includes a hollow structure, and a free and a threaded member projecting in the hollow structure from both ends. The optical fiber is mounted in tension inside the hollow structure through longitudinal fiber-receiving bores in both members, and has an anchor point affixed to each member with the grating therebetween. The anchor point of the threaded member is provided outside of the hollow structure, making the device more compact. The free and threaded members are rotatable together to adjust the resonant wavelength of the grating, and a nut may be provided to allow a fine-tuning. The hollow structure, free member and threaded member have a coefficient of thermal expansion selected so that they together compensate for the temperature dependency of the Bragg wavelength.

    摘要: A method for designing an index profile suitable for encoding into a phase mask for manufacturing a complex optical grating is provided. The optical grating corresponds to a target index profile defining a target spectral response. A modified index profile is set equal to the target index profile and expressed as a function of an apodization and phase profiles. The modified index profile is iteratively further modified in order to provide the index profile suitable for encoding in the phase mask. This process creates side bands outside of a spectral region of interest, while maintaining the target spectral response within the spectral region of interest.

    摘要: A method for manufacturing a complex multi-channel optical grating using a phase mask is presented. A plurality of sub-gratings is designed, each having an individual spectral response designed to produce one of the channels of the multi-channel grating. The target profile of the grating is determined based on the combination of the index profiles of the individual sub-gratings, the target index profile defining a target spectral response of the multi-channel grating. A modified index profile having a smooth apodization profile but providing the same spectral response as the target index profile, at least within a spectral region of interest, is determined and encoded into the phase mask. The phase mask is then used to photoinduce the grating in a photosensitive medium.

    摘要: A device for measuring the draft of cigarettes comprises a vertical tubular body in which cigarettes are fed one by one. A first sphincter-member mounted inside the body is operable to prevent a cigarette from falling and stop it in a given position. A second sphincter-member positioned above the first member is actuated when the first member is released so as to hold the cigarette in the above given position. A seal is provided at the bottom side of the tubular body to define a gas-tight chamber with the second sphincter-member, and an orifice connected to a source of air under vacuum is formed in the body between the first sphincter-member and the seal.

    摘要: The method for scanning a turbid medium involves displacing an optical signal source over a first face of the medium and a corresponding optical detector over an opposite face from one respective spatial location to another. Each spatial location is associated with a corresponding input region on the first face and a corresponding output region on the opposite second face. The optical detector in response to optical signals detected from each of the output regions generates a primary set of image data, secondary and/or tertiary image data by scanning the turbid medium using input regions and output regions of different sizes. The various sets of image data obtained may be manipulated in any manner, namely subjected to a data processing technique, so as to, for example, highlight the differences or similarities between the images.
