Title: Laser diode drive circuit
Inventor: NAGANO KATSUMI
IPC: H01S5/0683
Filed: 1986-09-22
Abstract: PURPOSE:To control a photo output at a constant value as well as to make possible a high-speed operation by a method wherein the difference current between a photovoltaic current and a reference current is inverted and amplified and a forward current which is fed to a laser diode to be driven from a current source for bias is controlled by this output in such a way that the two become equal. CONSTITUTION:When a forward current If which is fed from a current source 2 for bias reaches a threshold current, lasing takes place and a photo output Po is produced, and after this the photo output Po is augmented in proportion to the forward current If. The difference current between a photovoltaic current Is which is produced in a photo diode PD and a reference current Iref is inputted in an amplifier 5 for inversion amplitude, this difference current is inverted and amplified and an output current Io is produced. A forward current which is fed to a laser diode to be driven from a current source for bias is controlled by this inversion amplified output and the photo output of the laser diode to be driven is controlled to have a constant value. Thereby, with a high-speed operating property obtained, the reduction of cost can be contrived.

Title: Plastic optical fiber
Inventor: HAYAMI HIROSHI
IPC: G02B6/00
Filed: 1986-09-19
Abstract: PURPOSE:To obtain the titled fiber having improved anti-chemical property by incorporating a material composed of polyfluorovinylidene or a specific copolymer and an organosilicon compd. which contains plural vinyl bindings in a molecule to a clad layer, followed by cross-linking said material by radiating the clad layer with an ionizing radiation. CONSTITUTION:The cross-linking method of the copolymer composed of polyfluorovinylidene or the copolymer of fluorovinylidene and tetrafluoroethylene or hexafluoropropylene which is the clad material in a general use, lies in mixing the polyfluorovinylidene series resin and the org. silicon compd. having plural vinyl bindings, followed by cross-linking the copolymer by radiating the copolymer with the ionizing radiation. As the most of the org. silicon compd. has the refractive index of at most 1.41, and the polyfluorovinylidene resin has generally the refractive index of <=1.40, even if the compounding amount of the org. silicon compd. increases to raise the cross-linking efficiency, the refractive index does not almost increase relatively, and the increasement of the refractive index almost neglects, whereby the optical transmission loss does not increase by cross-linking of the copolymer. Thus, the titled fiber having the low optical transmission loss and the good anti-chemical property is obtd., as the clad layer can be closs-linked without increasing the refractive index of the clad material.
