摘要： An SC-type optical PAD connector (4) has a ferrule (6) for accommodating a certain length of an optical fiber (5) which comprises a core containing a light absorbing dopant such as Co or V for adjusting the intensity of the received signal within a permissible range and a photosensitive dopant such as Ge or Sn for selectively reflecting the input light and provided with a chirped grating, which is a periodic modulation structure for the refractive index, in the longitudinally middle portion and a cladding formed outside of the core and having a refractive index smaller than that of the core. The certain length of the optical fiber (5) is protected by the ferrule (6) and fitted in a housing (7) and the connector (4) has one end formed into a male connection terminal and the other end formed into a female connection terminal.

摘要： Light, which has been produced by a semiconductor device (11) and has wavelengths falling within the range of 630nm to 680nm, is propagated through a plastic fiber (12) provided with a core (12a) containing a polymethyl methacrylate as a principal constituent. The temperature of the semiconductor device is adjusted by a temperature adjusting system (21) comprising a heater (22) for heating the semiconductor device, a temperature detector (thermistor) (17) for detecting the temperature of the semiconductor device and feeding out a temperature detection signal (S), and a control circuit for controlling actuation of the heater in accordance with the temperature detection signal in order to set the temperature of the semiconductor device at a predetermined target value that is lower than the highest temperature assumed to occur under an environment, in which the semiconductor device is located.

摘要： The invention relates to optical fibers, and systems containing optical fibers. The invention provides an optical fiber that includes a core (110), a cladding (120), a region (130a, 130b, 130c, 130d) and a layer (140) that surrounds and contacts cladding (120). The core (110) enhances pump energy absorption by interacting with pump energy at a desired wavelength and the cladding confines the pump energy at wavelength so that the pump energy can propagate along the fiber and can interact with core (110).

摘要： An optical waveguide is provided. Specifically, a low loss isotopic optical waveguide that comprises a core region having a first refractive index profile by virtue of comprising a first mixture of isotopes of at least one element, and a cladding region having a second refractive index by virtue of comprising a second mixture of isotopes of said at least one element, is provided. Preferably said at least one element comprises silicon and/or oxygen. The optical waveguide may further include germania dopant in the core.

摘要： A method of joining a first optical fibre (110) to a second optical fibre (130) comprises the steps of: (i) providing a preform element (10) comprising material defining a primary elongate cavity (40); (ii) inserting the first optical fibre (110) into the primary cavity (40) to form a preform (125); and (iii) drawing the second optical fibre (130) from the preform (125); wherein, the second optical fibre (130) includes a core region comprising material that has been drawn from the first optical fibre (110).
