    摘要： An active optical device comprises a glass, waveguiding structure disposed on a substantially planar principal surface of a substrate. The structure includes a silica-based, erbium-doped active core. The active core has an absolute erbium concentration of at least about 0.5.times.10.sup.20 atoms per cubic centimeter, and a radiative lifetime of the erbium lasing level of at least about 5 milliseconds. The active core does not contain significant amounts of alkali metals or alkaline earth metals but does contain at least two modifier metals. Also disclosed is a method for forming an active optical device, including the step of depositing an erbium-doped active core by sputtering.

    摘要： An optical receiving system includes a Fresnel lens optically coupled to a detector via a tapered concentrator. The Fresnel lens is adapted to receive an electromagnetic signal and has a Fresnel focal point. The tapered concentrator has a first end surface area larger than a second end surface area. The detector has a sensing surface area oriented to receive the electromagnetic signal emerging from the tapered concentrator.

    摘要： An optical fiber connector plug includes a housing through which extends a cable containing at least one optical fiber. A ferrule, which is supported by the housing, is provided for receiving the optical fiber. The ferrule has a mating facet and an opposing rear facet located in the housing. The ferrule has at least one guide pin thru-hole and at least one optical fiber thru-hole extending between the mating facet and the opposing rear facet. The guide pin thru-hole has an opening portion extending inward from the mating facet. The opening portion is tapered outward to meet the mating facet in an oblique manner such that the opening portion has a diameter in the plane of the mating facet that is greater than a diameter of a remainder of the guide pin thru-hole.

    摘要： In the method and apparatus for controlling the power level of a laser signal in free space communication, a communication terminal transmits an output laser beam into free space and also receives information, through a channel that is not free space laser based, about the power of the output laser beam measured at a distance and at different times. The terminal determines whether a drop in the power of the output laser beam measured at the distance is due to atmospheric effects based on the received information. The terminal increases the power level of the output laser beam to a desired level if the power drop is determined to be due to atmospheric effects. On the other hand, the terminal lowers the power of the output laser beam to a predetermined level if the power drop is determined to be due to blockage thus avoiding harm to accidental observers that might intrude into the path of the laser beams.

    摘要翻译： 在用于控制自由空间通信中的激光信号的功率电平的方法和装置中，通信终端将输出激光束发射到自由空间中，并且通过不是以自由空间激光为基础的信道来接收信息， 在一段距离和不同时间测量输出激光束。 终端确定在距离处测量的输出激光束的功率的下降是否是由于基于所接收的信息的大气影响。 如果确定功率降是由于大气效应，则端子将输出激光束的功率电平增加到期望的水平。 另一方面，如果断电被确定为由于阻塞而导致输出激光束的功率降低到预定水平，从而避免对可能侵入到激光束路径中的意外观测器的危害。
