  • Publication number: 20240055825
    Abstract: A control system for a laser source includes a light extraction unit connected to a signal transmission port of a pump combiner of the laser source, and a microprocessor. The signal transmission port detects a leakage light signal from an optical resonator via the pump combiner to obtain a light parameter. The microprocessor unit is configured to determine an output power of the output laser signal based on the light parameter, and when it is determined that the output power differs from a preset power value, transmit an adjustment signal for adjusting an input power supplied to a plurality of pump sources.

  • Patent number: 8368162
    Abstract: The present disclosure provides a high-speed laser power converter (LPC). The LPC is able to be cascaded. The LPC has a high-speed photodiode (PD) performance even operated under a forward bias operational voltage. Thus, the present disclosure can generate power (instead of consume power) during high-speed data transmission in an optical interconnect (OI) system using 850 nano-meters (nm) wavelength vertical cavity surface-emitting laser (VCSEL).

  • Patent number: 8306428
    Abstract: An optoelectronic switch using millimeter wavelength (MMW) is provided. An r voltage pulse is applied to a device under test (DUT) for switching the photo-generated MMW power The DUT is operated under reverse bias. An optical light source with modulated MMW envelop is injected on to DUT for MMW power generation. Thus, based on change of the reverse bias, speed is violently changed and the MMW optoelectronic switch is thus obtained.

  • Patent number: 8288808
    Abstract: The present disclosure uses at least two cascaded photodetectors. Device area is increased to provide a bigger current than a single photodetector under the same bandwidth. Hence, bandwidth efficiency (BRP) and saturation current-bandwidth product (SCBP) are improved for a high speed, a high responsivity and a high bandwidth with simple structure and low cost.

  • Patent number: 7320115
    Abstract: A method is disclosed for identifying a physical failure location on an IC without using layout-versus-schematic (LVS) verification tool. In the method, the integrated circuit is tested with one or more test patterns to identify a failure port thereon. Hierarchical information of the failure port is generated through the test patterns. A physical location of the failure port in a layout of the integrated circuit is identified through a relation between the hierarchical information and a floor plan report. Layout information of a routing path associated with the physical location of the failure port is retrieved from a layout database.

  • Patent number: 6808985
    Abstract: A method of fabricating ROM products through the use of embedded flash/EEPROM prototypes is disclosed. This is accomplished by first forming a Flash/EEPROM prototype, performing programming simulations on the prototype, developing a ROM code and mask, and then forming a ROM product in the same manufacturing line by skipping certain Flash/EEPROM steps and then implanting the ROM code into the final ROM product. The method improves turn-around-time in the manufacturing line, and reduces cost to the customer. A method of doing business is also disclosed directed to providing ROM products to a customer without much redesign time and effort on the part of the customer.
