    摘要: The present invention discloses a low-cost light source for optical transmission systems and optical networks based on wavelength-division multiplexing (WDM) technology. A light source in accordance with the present invention is implemented by externally injecting a narrow-band incoherent light into a Fabry-Perot laser diode (F-P LD). After injection of narrow-band incoherent light, the output of F-P LD becomes wavelength-selective rather than multi-mode and the output wavelength of F-P LD coincide with the peak wavelength of the injected incoherent light.Multi-channel WDM light sources according to the present invention can be implemented using a single broadband incoherent light source and plurality of F-P LDs. An optical transmission system for upstream signal transmission in an passive optical network using the light source according the present invention is also disclosed.

    摘要: A soft mold and a method for fabricating the same are disclosed. A master mold that has a pattern on a substrate is first formed. A first liquid high polymer precursor is formed on the master mold and then partially cured. A support film having high UV transmittance is attached to the partially cured high polymer. The attached support film and the partially cured high polymer are treated with a coupling agent and a second liquid high polymer precursor is formed on the partially cured high polymer and the support film. The second liquid high polymer precursor and the partially cured high polymer are then fully cured to form a mold. The fully cured mold is stripped from the master mold to form a soft mold having a predetermined shape on one surface.
