摘要： A power amplifier comprises a common source amplification stage and a first common gate amplification stage. The common source amplification stage includes a common source transistor for receiving a radio frequency (RF) input signal via a gate. The first common gate amplification stage is connected in cascode between a variable supply voltage source and the common source amplification stage, and amplifies an output of the common source amplification stage. The first common gate amplification stage includes a first common gate transistor, and a first gate bias controller configured to generate a first divided voltage based on a variable supply voltage of the variable supply voltage source, and to supply a first gate bias voltage generated by buffering the first divided voltage to a gate of the first common gate transistor.

摘要： Using lateral physical modulation, the optical properties of VCSELs can be stabilized and controlled by spatially varying the characteristics of the device material. This results in stabilization of the linewidth, the numerical aperture, the near and far field, as a function of bias and temperature. A VCSEL includes a substrate, an active region sandwiched between an upper and lower distributed Bragg reflector (DBRs), and electrical contacts. A light emission property e.g. the index of refraction, may be varied by patterning or texturing the surface of the substrate prior to growth of the epitaxial DBR layers or at least one layer of either the upper or lower DBRs, or by inserting a non-planar layer.

摘要： An optical assembly for use in an optical telecommunications system and method for aligning the optical assembly. The assembly uses a pair of ball bearings to support an optical fibre on a baseplate. The optical fibre is aligned with respect to an optical device and then the first ball bearing is inserted and welded in place. The fibre alignment is then fine tuned and the second ball bearing is inserted and welded in place, thereby providing a simpler and more accurate method of aligning an optical fibre to an optical device.

摘要： A system side interface of a PHY chip used in conjunction with a 100 GBASE backplane, sends and receives data using an NRZ signal format, but at a data rate of between about 26.5 Gbps/per lane to 27.2 Gbps/per lane, which is consistent with the PAM 4 signaling protocol. Thus, chip-to-chip communications between a PHY chip and a switch or controller chip can use an “overclocked” NRZ signaling format, reducing the amount of logic needed, which in turn can reduce signal latency, and reduce the chip area and power consumption required to implement the logic.
