摘要： Un lente índice de gradiente (GRIN) acopla la luz que proviene de una fibraoptica individual a un paquete de fibras o directamente al puerto de entrada de un dispositivo de iluminacion, tal como un dispositivo médico de iluminacion; la fibra optica individual provee un haz de luz de alta intensidad que tiene una AN alta; una cara de entrada del lente GRIN está colocada adyacente a una abertura de salida de la fibra dentro del campo cercano de la fibra, y recibe de esta manera un haz que tiene una seccion transversal substancialmente uniforme, en lugar de una seccion transversal Gaussiana como ocurriría si el lente GRIN estuviera colocado en el campo lejano de la fibra; una cara de salida del lente GRIN está colocada adyacente al paquete de fibras o puerto de entrada del dispositivo de iluminacion; como tal, el lente GRIN forma una imagen en forma efectiva de la abertura de salida de la fibra de la abertura de entrada del paquete de fibras como el puerto de entrada; las características opticas del lentre GRIN, incluyendo su longitud y variacion radial en el índice de refraccion, se seleccionan para reducir la AN de la emision de luz que proviene de la fibra hasta un valor adecuado para usarse con el dispositivo de iluminacion; se describe un acoplador optico que emplea al lente GRIN, así como un sistema optico completo que incluye una fuente de luz, un acoplador fuera de eje para acoplar la luz a la fibra, un lente de índice de gradiente y un endoscopio; se describe también un alojamiento mecánico para sostener a la fibra individual y el lente GRIN, y para facilitar la conexion a un paquete de fibras o puerto de entrada.

摘要： A dispersion transformer (14) is provided for limiting the data rate of an optical fiber transmission system. A transmission optical fiber (11), which connects a transmitter (Tx) and a receiver (Rx), may have a bandwidth much greater than that necessary to transmit a desired predetermined maximum data rate. The transmitted signal is connected to wavelength disperser means (15) which spatially separates the different wavelength components of the transmitted signal. Each wavelength component is then propagated with a different delay by optical fiber delay means (16-21). The wavelength component (λn) which propagates with the least delay through the transmission optical fiber (11) is subjected to the least induced delay in the optical fiber delay means (16-21) and that (λ₁) which propagates with the greatest delay through the transmission optical fiber (11) is subjected to the greatest induced delay in optical fiber delay means (16-21), the remaining components being subjected to intermediate delays. The delayed wavelength components are combined to form a series of broadened optical pulses (36).

摘要： In a method of effecting permanent end-to-end connections between a plurality of optical fibres 2,3,4..., e.g. the optical fibres of an optical fibre ribbon 1, and the optical waveguides 12,13,14... of an integrated optic device or chip 11, each optical fibre in turn is so arranged that its end 2ʹ to be connected protrudes beyond the ends of the other unconnected optical fibres with its end face spaced a short distance from the end face of the corresponding optical waveguide, accurate axial alignment of the core of the optical fibre and the corresponding waveguide is effected, curable adhesive is applied to the optical fibre and is permitted or caused to cure so that the optical fibre is permanently fixed with respect to the optical component, and these three steps are repeated for each immediately adjacent optical fibre and corresponding optical waveguide.

摘要： A fiber optic saturable absorber for processing optical signals is characterized by an optical fiber (20) from which a portion (40) of the cladding (36) is removed to form a facing surface (28). A light-absorbing substance (30) having non- linear light-absorbing characteristics is applied to the facing surface (28) such that a portion of the optical signal energy is transferred from the fiber (20) to the substance (30) where it is absorbed. The device selectively attenuates the optical signal and noise, and can be used to reduce pulse waveform distortion caused by pulse broadening and by amplification of system noise.

摘要： A light diverting device for diverting a part of the light energy transmitted through an optical conductor rod and for taking it out. A light diverting device comprised of a first optical conductor rod having a through-hole in a radial direction; a second and a third optical conductor rod tightly inserted into the through-hole, the edge surfaces of the second and third optical conductor rods in the through-hole being formed so as to be engaged with the inclined surfaces; a fourth optical conductor rod fixed on the outer circumferential surface of the first optical conductor rod so as to cover the inserted portion of the second optical conductor rod. Optical oil is enclosed in a space of the through-hole between the inclined surfaces of the second optical conductor rod and that of the third optical conductor rod. A cover member covering the edge portion liquid-tightly at the opposite side to the inclined surface of the third optical conductor rod and firmly fixed on the outer circumferential surface of the first optical conductor rod.

摘要： An optical fiber having an elliptical lens comprises a main body (10) and two fiber pieces (15, 16) embracing one end of the main fiber body (10) therebetween and extending substantially in parallel with said main fiber body (10). The elliptical lens is formed by fused ends of the main fiber body (10) and the fiber pieces (15, 16). A method of producing an optical fiber having an elliptical lens comprises steps of arranging two fiber pieces (15, 16) substantially in parallel with and on both sides of an optical fiber (10) and adjoining and embracing one end of the optical fiber (10) and heating and fusing ends of the optical fiber (10) and the fiber pieces (15, 16) to form the elliptical lens by the fused portions thereof with the aid of surface tension. Light beams are effectively introduced into the optical fiber through the elliptical lens.
