Optoelectronic IC

Custom and Semicustom Optoelectronic ICs

EM Microelectronic's optoelectronic product line encompasses a broad range of products, with the common elements being optical-input and efficient electronic signal processing. We deliver market-driven customizable solutions for your applications.

The EM engineering team has many man-decades of experience in optoelectronic products, during which we have developed the full range of expertise needed to achieve the right product for your optoelectronic application

Examples of Optoelectronic-related Capabilities
* 20 picoAmp Photocurrent Optical Receiver (ESSCIRC 1997)
* Thermoelectric Infrared Sensors and Low-noise amplifiers (ESSCIRC 1996 & JSSC 1997)
* Wide-bandwidth Low-noise optical receivers (DC – 150MHz)
* In-pixel custom signal processing (2-D calculations faster with less power)
* Differential Sensor auto-normalization: full wide band calculation of the normalized Output = (A-B)/(A+B)
* Low Power (12mW) CMOS VGA Image Sensor
* High-Speed (>5000 frames/sec) CMOS Image Sensor
* High-dynamic range signal handling and "electronic shutter" exposure timing
* Linear, logarithmic, or other response curves
* Optical Chip-on Board, and Optical Chip-Scale packaging
* Optical Module (including lenses, filters, etc) design and low-cost production
* System level analysis and simulation for optimum cost/performance tradeoffs

CD/DVD Photodetector/Amplifier ICs
EM has a family of Optoelectronic ICs called PDICs and XOEICs^® for high performance CD and DVD products. Our parts have industry-leading characteristics for low-noise (-80dBm at the output), wide-bandwidth (DC to 150MHz), and DC accuracy.
EM is the only licensed manufacturer of Multi-beam^® pickup ICs that enable extremely fast DVD drives. Multi-beam^® optical drives are leading-edge products entering manufacturing now and will be available in mass volume soon.

Computer Interface Products
EM supplies more than 50% of optical elements for mice and trackballs for the entire world; being the highest-quality and highest-volume supplier in that market. Further, EM has held that position since the mid '90s, with innovative low-cost, mass-produced products.

EM continues with exciting new product developments for the human-computer interface market. The latest generation of mice and trackballs are intelligent cameras with complex signal processing performed within the imager IC.

"Smart-Sensor" Products
The wide variety of optoelectronic IC developments have established EM as a world leader in this area of photons-to-information integrated circuitry. We embed complex signal processing into the pixel elements or onto the same IC as the photosensor in order to achieve the optimum tradeoff of cost/performance.

The EM team contains the required system-level expertise to develop a custom photo-processor for your application. We perform the system analysis and application-simulation, specification, detailed design, verification, fabrication, packaging, evaluation, and test development that gives you the complete solution to your application.

Packages & Modules
A key challenge in cost-effective optical ICs is providing the right package solution at the right price. EM provides a wide variety of standard optical package options; plus low-cost optical-chip-on-board (OCOB) as well as other custom package solutions, including optical chip-scale packages.

EM's staff also has created a wide variety of high-volume modules that include optical elements as well as electronic components into a single cost-effective solution. EM can be a one-stop shop for your entire module, with the full range of design support, from the optical design expertise to the mechanical packaging expertise necessary for low-cost high-volume applications.
