    摘要: An apparatus and method for making n different types of optical amplifiers on one manufacturing line, n being equal to 2 or more. The method includes providing a supply of at least four functional groups of subunits for each of the circuits which comprise each of the optical amplifiers to be made, where at least one functional group contains at least n different types of sub-units, and where each of the sub-units in three of the functional groups includes a pluggable optical connector half and where each of the sub-units of the fourth of the functional groups includes three pluggable optical connector halves. The method further includes selecting a specific sub-unit from each of the four functional groups and plugging together each of the selected subunits to form an optical amplifier having the desired specification.

    摘要: Apparatus for packaging a fiber optic device along with electronic and opto-electronic components upon a printed circuit board. Bend members having arcuate shaped guide surfaces for directing fibers between various components are strategically mounted upon the top surface of the board. Passive fiber optic components are also mounted upon support means between bend members so that the fibers entering and exiting the passive component run tangent to the bend radius of the bend members. The radius of curvature of the bend members is within the bend tolerance of the fibers used in the device. The bend members and support members are formed of a material having a thermal coefficient of expansion that is about equal to that of the board material whereby thermally induced stresses on the board mounted components are minimized.

    摘要: A package for a high power semiconductor laser comprising a hermetically sealed container filled with a dry gaseous medium containing oxygen. The presence of oxygen in the laser atmosphere is counter to standard practice in the art which teaches the use of an atmosphere of a dry inert gas. The package also includes a getter for organic impurities, e.g., a getter composed of a porous silica or a zeolite. The hydrogen content of the materials used to form the package are reduced by baking at an elevated temperature for an extended period of time, e.g., at 150.degree. C. for 200 hours.

    摘要: The variables and parameters previously understood to affect the gain spectrum of an optical amplifier 13 were: (1) the wavelengths to be amplified; (2) the input power levels at those wavelengths; (3) the characteristics of the amplifying medium 20; (4) the insertion loss spectra of the amplifier's components, including any filter(s) used for gain flattening; (5) the pump band chosen to pump the amplifying medium 20; and (6) the total amount of pump power supplied in the chosen pump band. An additional fundamental variable has been identified which can be used to control the gain spectrum of an optical amplifier 13, namely, the center wavelength of the spectrum of the pump's output power within the chosen pump band. Methods and apparatus for using this variable for this purpose are disclosed.For example a, transmission system is disclosed having a transmitter 11 and a receiver 10 connected by an optical fiber 12. A plurality of optical amplifiers 13 are located along the optical fiber 12 to amplify signal channels between the transmitter and receiver. Each of the amplifiers has a pump light source 21, the wavelength of which is such that contributions to differential gain due to pump light wavelength related effects is substantially reduced.Also disclosed is a WDM transmission system having a transmission path including a concatenation of laser diode pumped optical amplifiers 13 wherein the gain spectrum of an amplifier is controlled at least in part by a feedback loop regulating the temperature of its laser diode pump 21. The feedback loop may for instance derive its control signal from a measure of the drive current applied to the pump, of the emission wavelength of the pump, or of the disparity between the power output from the amplifier in one of the multiplexed signal channels and that from at least one other of the channels.
