摘要： A laser (15) is mounted on a planar surface of a monocrystalline silicon mounting member (12). A spherical lens (20) is mounted in a monocrystalline silicon cover member (13) which, when abutted and registered to the mounting member (12), aligns the spherical lens with the laser so that the output light can be projected along a precise predetermined path. The spherical lens (20) is mounted in a first V-shaped groove (31) which is made in the cover member by masking and etching. A second V-shaped groove intersects the first groove and defines a V-shaped edge in one side of the first groove. The spherical lens is then seated in the first V-shaped groove such that it bears against two points of the V-shaped edge and against one side wall (35) of the first V-shaped groove. A second lens (19) is mounted in the cover member in the same manner as the first lens and directs laser light from a rear facet of the laser to a mirror 30 and hence to a photodetector (21) mounted in the cover member.

摘要： An article according to the invention comprises two bodies that are joined together by means of a compression bond, such as to form an enclosure. One of the bodies comprises a (exemplarily Au-covered) textured surface region, and the other body comprises a (exemplarily Au) "O-ring" positioned such as to mate with the textured region, substantially surrounding the enclosure. The textured region comprises at least one (typically two or more) "ridge" that substantially surrounds the enclosure and that, after joining of the two bodies by compression bonding, provides a leakage barrier. Optional ridges between said two or more enclosure-surrounding ridges can further reduce the probability of leakage. The bodies exemplarily are Si bodies, with the enclosure serving to provide a controlled environment for a semiconductor laser. In another exemplary embodiment, the article is a flat panel field emission display.

摘要： Disclosed is a laser/fiber mount that can advantageously be used in laser transmitter packages for a variety of purposes, including pump laser packages for optically amplified optical fiber transmission systems and fiber-to-the-home systems. Both laser and fiber are attached to the same unitary body, preferably a Si body. An integral heater serves to melt a quantity of solder that serves to bond the fiber to the body after alignment of the fiber to the laser. A relatively thick dielectric layer underneath the heater provides a large thermal impedance, insuring that the temperature of the unitary body is at least 50.degree. C. (preferably 150.degree. C.) less than that of the solder.

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').
摘要翻译：锥形光波导（33'）可以通过使用光刻掩模和蚀刻来在衬底（21）上限定具有基本上均匀的厚度和锥形宽度的第一聚合物结构（22）来容易地制成。第一聚合物结构被充分加热以在整个长度上形成弯液面。流动性导致材料重新分布自身，使得不是具有均匀的厚度，而是具有随其宽度而变化的厚度; 因此，第一聚合物结构的厚度以及宽度变得逐渐变细。将第一聚合物冷却并硬化以形成第二聚合物结构（22'），其具有如锥形光波导所需的锥形宽度和锥形厚度。第二聚合物结构本身可以用作锥形光波导，或者可以用于控制底层基板的反应离子蚀刻。在后一种情况下，锥形第二聚合物结构的构造被复制在例如可用作玻璃锥形光波导（33'）的玻璃基板中。

摘要： A package that protects an optical fiber from strain or controls the strain to which the fiber is subjected for a desired effect and a method for making the package are disclosed. The package is a sleeve with an internal passage in which a portion of an optical fiber is placed. The optical fiber and the sleeve are made of materials with coefficients of thermal expansion that are the same or different.If the coefficients of thermal expansion are the same, the package protects the fiber from certain strains brought about by a change in temperature that would otherwise result if the package and the fiber were made of different materials. However, by selectively mismatching the coefficients of thermal expansion of the package and the fiber, a change in temperature can be used to bring about a desired change in the wavelength of a grating written in the fiber. The optical fiber is fixed in the sleeve by epoxy or other adhesive means at least at one point in the internal passage of the sleeve.
