Abstract: A diffusing function and a lens function are provided on a single surface. Such a structure may be formed from a computer generated hologram including free form regions having a phase shift associated therewith, i.e., the computer generated hologram being shifted within the free form regions by the phase shift relative to the computer generated hologram outside the free form regions. When the computer generated hologram includes zero and .pi. regions, the zero and .pi. regions may be transposed within the free form regions.

The exposed end faces of the optical rods are patterned so that each of the exposed end faces has a three-dimensional pattern formed thereon. These patterned optical rods can then be separated and used in the fabrication of optical systems.

Abstract: A laser diode power controller, and method, are disclosed. The controller can be implemented entirely in CMOS technology due to the simplicity of its quasi-decision-based control routines. The control routines involve the use of a window comparator which determines whether the measured power level of a laser diode falls within a desired range of values. The simplified control routines are also manifested by the use of digital registers to set the desired current values that are to be output to the laser diode and monitor diode. The modulation current supplied to the laser diode exhibits much lower noise levels because the modulation digital to analog converter (DAC) By supplying a continuous current that is selectively switched between the laser diode and a dummy load, much less noise is induced in the power supply than if it had to respond to large changes in modulation current, i.e., OFF (zero) and ON (desired Imod).

Abstract translation: 公开了一种激光二极管功率控制器和方法。 由于其准基于决策的控制程序的简单性，控制器可以完全以CMOS技术实现。 控制程序涉及使用窗口比较器，其确定激光二极管的测量功率电平是否落在期望的值范围内。 简化的控制程序也通过使用数字寄存器来设置要输出到激光二极管和监视二极管的期望电流值来体现。 提供给激光二极管的调制电流显示出低得多的噪声水平，因为调制数模转换器（DAC）通过提供在激光二极管和虚拟负载之间有选择地切换的连续电流，在电源中引起更少的噪声 如果它必须响应调制电流的大的变化，即OFF（零）和ON（所需的Imod）。

A method of forming an achromatic diffractive optical element is also provided which includes the steps of determining a first data set comprising a plurality of discrete phase values and discrete transition values and selecting from the first data set phase values and transition values to form a second data set for defining first and second holograms. A discrete value of the second data set is then replaced by another discrete value from the first data set. A change of an optical system error function is then determined responsive to the replacement in the second data set. If the error function is reduced, the new data set is retained.

Abstract: A multichip module having high density optical and electrical interconnections between integrated circuit chips includes a substrate overlaying an array of integrated circuit chips. An optical transmitter generates a first optical beam through the substrate and an optical detector receives a second optical beam through the substrate. A hologram is positioned in the path of at least one of the first and second optical beams. An array of electrical contact pads is located on the substrate corresponding to the array of electrical contact pads on the respective integrated circuit chips. A pattern of electrical interconnection lines is located on the substrate for electrically interconnecting the integrated circuit chips. A solder bump between electrical contact pads on the substrate and on the integrated circuit chips establish electrical connections between the substrate and the integrated circuit chips, and also facilitate alignment of the integrated circuit chips with respect to the substrate. The optical transmitter and detector may be mounted on/in the substrate or on/in the integrated circuit chips. The optical transmitter and detector may also be used to provide optical connections external to the microelectronic module, using a holographic substrate to optically link modules. The substrate may also be used to establish optical alignment of the hologram to an underlying optical emitter and/or optical detector without establishing electrical connections thereto.
