摘要： A holographic interference exposing device using a visible laser source and a chopper to easily align the optical system while confirming the light path of the laser beam with the naked eye. The exposing device comprises a main laser source generating a short wavelength laser beam, a beam splitter for splitting the laser beam into two laser beams to cause a difference in the light path of the laser beam and to form an interference fringe on a semiconductor substrate, mirrors for guiding the laser beam to the beam splitter, and mirrors for focusing the two laser beams on a surface of the semiconductor substrate, an auxiliary laser source generating a long wavelength laser beam, and a chopper making the light path of the long wavelength laser beam get together with that of the short wavelength laser beam. The auxiliary laser source generates a visible laser beam having a wavelength longer than that of an ultraviolet laser beam.

摘要： A node apparatus of such a ring communication network including buffers capable of improving a performance of the ring communication network and yet maintaining a global fairness in use of a ring communication network bandwidth among nodes, and a method for controlling the node apparatus. The node apparatus includes a receiver unit for receiving packets and slots from a ring, an ordering buffering unit for ordering the packets, a receiving queuing unit for temporarily storing messages of the packets to be sent to a host, a trunk buffering unit for temporarily storing packets to be transmitted to other nodes and then relaying the stored packets, a transmitting queuing unit for storing messages to be transmitted to the ring, and a transmitter unit for transmitting packets and messages in a medium access control manner. The control method includes the first step of checking about a destination node for a packet received to a node, the second step of processing the packet when the destination node corresponds to the packet-received node, the third step of processing the packet in a manner different from the second step when the destination node corresponds to a node other than the packet-received node, the fourth step of processing the packet at an empty state and the fifth step of processing the packet at a seizure state.

摘要： A laser package comprises a laser diode source having a first Fabry-Perot cavity between a highly reflective back facet and low reflective front facet for providing a first light output for an optical application. A light monitor is positioned adjacent to the back facet and aligned to receive a second light output from the laser diode back facet. A pigtail fiber having a lensed fiber input end is positioned from the laser diode front facet to form an optical coupling region and is aligned relative to the lasing cavity to receive the first light output into the fiber, the light output exiting the package for coupling to the application. A portion of the first light output from the lasing cavity is reflected off the lensed fiber input end with a portion directed back into the lasing cavity and another portion reflected off of the laser diode front facet. The front facet forms with the lensed fiber input end a second Fabry-Perot cavity generating light which is periodically in and out of phase with the light generated in the first Fabry-Perot cavity due to changes in the length of the second Fabry-Perot cavity caused by package ambient temperature changes so that a tracking error is generated in a signal developed by the light monitor. Thus, this invention provides several ways to suppress the formation of the second Fabry-Perot cavity.

摘要： A microlens on the end of an optical fiber has reduced back reflections to a light source, such as a pump laser diode. In a particular embodiment, the microlens is lapped on two radii, at least one of which is offset from the center axis of the fiber, to form a point on the end of the fiber, thus reducing a surface for reflecting light back to the light source. In another embodiment, the microlens is formed with two different side surface angles to accommodate misalignment of the light source to the fiber mount. In another embodiment a Fresnel lens structure on the end of the fiber operates optically as an angled chisel lens.
