Latest Patents
One of Chen's latest patents is the "Thermal Compensated Fused-Fiber Dense Wavelength Division Multiplexer." This invention provides a structure and method to compensate for temperature changes affecting wavelength shifting in dense wavelength division multiplexing (DWDM). By reducing tension in the fused-fiber DWDM when temperatures rise and increasing tension when temperatures fall, the device stabilizes wavelength shifts across a range of operating temperatures. The DWDM is designed to be enclosed in a protective package and connected to substrates with different thermal expansion coefficients. This innovative design allows the fused-fiber portion to exhibit negative thermal expansion, minimizing temperature-induced wavelength shifts through passive thermal compensation.
Another significant patent is the "Fused-Fiber Multi-Window Wavelength Division Multiplexer." This invention improves the stability and performance of multiplexers in dense WDM applications. It utilizes an unbalanced Mach-Zehnder Interferometer with first and second fused-fiber couplers connected by optical fibers of varying lengths or refractive indices. The design allows for tension to be applied to the fused-fiber multi-window WDM, optimizing the desired passband before it is mounted within a protective substrate. A passive thermal compensation technique is also employed to minimize thermal effects on the passband wavelengths.
