Abstract: Devices and method for forming a switch including a heater layer including a first heater pad, a second heater pad, and a heater line connecting the first heater pad and the second heater pad, a phase change material (PCM) layer positioned in a same vertical plane as the heater line, and a floating spreader layer including a first portion positioned in the same vertical plane as the heater line and the PCM layer, in which the first portion has a first width that is less than or equal to a distance between proximate sidewalls of the first heater pad and the second heater pad.

Abstract: A single wavelength fiber-optic communication system that mixes an Ethernet signal with a radio frequency signal is disclosed. The system includes an Ethernet signal module, a radio frequency signal module, a mixer module and a receiver module. The Ethernet signal module provides an Ethernet signal. The radio frequency signal module provides a radio frequency signal. The mixer module provides an optical mixed signal by means of mixing the Ethernet signal with the radio signal at a single wavelength. The receiver module transforms the optical mixed signal into the radio frequency signal and a digital signal that contains the Ethernet signal.

Abstract: The present invention is an optical fiber system and method for carrying both CATV and Ethernet signals. The digital signals are translated into higher band by a direct up/down conversion so that analog signals and digital signals are treated as different frequency bands of electrical signals. Then, all the signals are mixed/divided by a power combiner/divider. And then, by using optoelectronic devices, the signals are processed with optoelectronic conversion. The converted optical signals are transmitted in a fiber or a related optical channel having low channel loss yet high capacity. To sum up, the present invention can transmit digital signals together with analog signals in a single wavelength to save the cost of an optical signal system and to provide a convenience on rearranging the system.
