摘要： A method and system for enhanced demolding of injection molded optical devices are disclosed. In one embodiment the system includes a metal moldplate without a coat of release layer and a curing device that generates high intensity pulses of UV light. The method includes: providing a moldplate made of a predetermined moldplate material; directly injecting optical material into cavities of a moldplate without a release layer; rapidly curing the injected optical material with high intensity pulses of UV light such that a predetermined optical device is formed; and separating the thus formed optical device from the cavities of the moldplate due to a differential thermal expansion between the optical device material and the moldplate material.

摘要： Methods and systems for fabrication of injection molded optical components. In one embodiment, a moldplate with cavities receives injected optical material within walls of the cavities. The cavities are designed with a geometric profile approximately corresponding to a optical profile of an optical element to be formed therein. When molten optical material is injected into the cavities of the moldplate, the injected optical material forms a meniscus due to surface tension between the optical material and the wall of the cavities. The meniscus thus provides a shape corresponding to the predetermined optical profile. The optical material is then rapidly cured with actinic radiation, and a desired optical element with high-precision dimensions is formed within the cavities of the moldplate. In some embodiments, the moldplate is spun such that the meniscus is adjusted to match the predetermined optical profile within a certain tolerance.

摘要： Feedback control of a target system is provided which utilizes the imposition of a periodic modulating signal onto a command signal of a controller. The command signal with the period modulating signal imposed thereon is input to the target system to be controlled. A response of the target system to a manifestation of the periodic modulating signal in the command signal is detected, and a feedback signal is produced from the detected response. The periodic modulating signal and the feedback signal are processed together to produce an error signal, and the command signal is modified in accordance with the error signal to drive the current state of the target system toward a desired state, wherein the periodic modulating signal facilitates control of the target system.

摘要： A wavelength-locked loop servo-control circuit and methodology that enables real time mutual alignment of an electromagnetic signal having a peaked spectrum function including a center wavelength and a wavelength selective device implementing a peaked passband function including a center wavelength, in a system employing electromagnetic waves. The circuit comprises a mechanism for applying a dither modulation signal at a dither modulation frequency to the electromagnetic signal, and inputting the dither modulated electromagnetic signal to the wavelength selective device; a mechanism for converting a portion of the dither modulated electromagnetic signal to an electric feedback signal; a mechanism for continuously comparing the feedback signal with said dither modulation signal and generating an error signal representing a difference between a frequency characteristic of the feedback signal and a dither modulation frequency; and a mechanism for adjusting the peaked spectrum function of the electromagnetic signal according to the error signal. The center wavelength of the electromagnetic signal and the wavelength selective device center wavelength become aligned when the frequency characteristic of the feedback signal is two times the dither modulation frequency.

摘要： A receiver portion of a multichannel communications link uses optical components to receive data in parallel. Further, the receiver portion of the link provides various functions, including clock recovery, clock-to-data alignment and deskewing. The clock-to-data alignment provides for a dynamically adjusted clock that is used to regulate the output flow of data from the receiver portion, either in parallel or in series.

摘要： An arrangement for tuning a micro-electro-mechanical (MEM) laser center wavelength to exactly match the passband of its associated filter. A dither wavelength locked feedback loop dynamically adjusts the position of the MEM element, and hence the laser, wavelength, to keep it nominally centered at the filter passband peak. The dither wavelength locked feedback loop compensates for many internal variables of the laser, filter, and the MEM with a single mechanism that stabilizes the laser and locks the wavelength to any desired value.

摘要： Obtains a large increase in the number of fiber optic inputs/output (I/O) lines connectable to a module by enabling edge connection of multiple clusters of optical fibers to be connected around a module. Each connector connects a cluster of optical fibers in a small dimension of space on the module. Many distinct pluggable connectors may be provided along one or more edges of a module. The optical-fiber cluster connectors are embedded in indentations around the edges of a multilayer glass/ceramic (MLGC) multi-chip module (MCM), which may be a thermal conduction module (TCM), containing an integrated photonic receiver and/or transmitter for each fiber. Each connector supports a large number of fibers from a single cable, and a large number of connectors may be provided in a single module. Easy plugging and unplugging is obtained for each connector without interferring with any existing cooling apparatus or I/O pins of the module. Receptacle and plug assemblies which hold the fibers in respective key V-grooves etched in silicon members which carry and interlock each fiber in each receptacle. Alignment and locking means is provided in each connector for aligning a plug's array of fibers with corresponding receptacle fibers in one or more angled groove(s) in a receiving receptacle. Thermal coefficients of expansion match between the silicon receptacle and the glass-ceramic substrate to guarantee the preservation of opto-mechanical alignments.
