摘要： Tapered optical waveguides (33') can be easily made by using photolithographic masking and etching to define on a substrate (21) a first polymer structure (22) having a substantially uniform thickness and a tapered width. The first polymer structure is heated sufficiently to form a meniscus along its entire length. The fluidity causes the material to redistribute itself such that, rather than being of uniform thickness, it has a thickness that varies with its width; consequently, the thickness as well as the width of the first polymer structure becomes tapered. The first polymer is cooled and hardened to form a second polymer structure (22') that has a tapered width and a tapered thickness as is desirable for a tapered optical waveguide. The second polymer structure itself can be used as a tapered optical waveguide, or it can be used to control the reactive ion etching of the underlying substrate. In the latter case, the configuration of the tapered second polymer structure is replicated in a glass substrate, for example, which then may be used as a glass tapered optical waveguide (33').

摘要： An optical module is provided for performing a prescribed function such as dispersion compensation, for example. The optical module is to be integrated between stages of a multi-stage rare-earth doped optical amplifier. The module includes an input port for receiving optical energy from one stage of the rare-earth doped optical amplifier and a rare-earth doped planar waveguide coupled to the input port. An optically lossy, passive element is provided for performing the prescribed function. The optically lossy, passive element is coupled to the planar waveguide for receiving optical energy therefrom. An output port is coupled to the optically lossy, passive element for providing optical energy to another stage of the rare-earth doped optical amplifier. The rare-earth doped planar waveguide has a first unsaturated absorption spectrum and the rare-earth doped optical amplifier has a second unsaturated absorption spectrum such that the ratio of the first to the second absorption spectrum is substantially wavelength independent within the spectral range of incoming and outgoing optical energy. The rare-earth doped planar waveguide has a length determined at least in part from a value of optical loss in the passive element and characteristics of the rare-earth doped optical amplifier.

摘要： The luminescent screen of a cathode ray tube includes an array of monocrystalline or amorphous phosphor rod-like elements which are covered with a reflective coating except for one end of each element which serves as an output face. The phenomenon of the light trapping is advantageously exploited to achieve enhanced brightness. The screen is illuminated with an electron beam which has an essentially oblong cross section and which is oriented along the elongated dimension of the elements. In one embodiment the elements comprise epitaxial Lu.sub.3 Al.sub.3 Ga.sub.2 O.sub.12 :Ce on the top of a YAG substrate, and a light absorbing layer of Lu.sub.3 Al.sub.3.5 Fe.sub.1.5 O.sub.12 is formed on the bottom of the substrate. A printer utilizing such a CRT is described. Also described is a configuration in which each of the rod-like elements functions as a laser.

摘要： In a CRT system the luminescent screen includes an ordered array of rows and columns of phosphor elements, illustratively made of single crystal material. Each element is surrounded on all sides (except the light output face) by reflective material. To enhance light extraction efficiency, the output face may be textured. An electron beam is made incident on the output face of selected ones of the elements and scans in two dimensions across the plane of the elements. Also described is an arrangement whereby the electron beam is made incident on the back surface of the elements opposite the output face.
