10-Gbps Upstream Transmission for WDM-PON Using RSOA and Delay Interferometer
10-Gbps Upstream Transmissio WDM-PON RSOA Delay Interferometer
2015/5/20
We demonstrate the transmission of 10-Gbps NRZ signals over 20-km standard single-mode fiber using an RSOA in a loopback configured WDM-PON system. Significant performance improvement is achieved usin...
High-sensitivity broadband micro-Michelson-interferometer based on an end-sphered hollow-core fiber
broadband micro-Michelson-interferometer nd-sphered ollow-core fiber
2015/5/15
We demonstrate a high-sensitivity broadband micro-Michelson fiber interferometer using a singlemode fiber end-spliced with a short (43.9μm) hollow-core end-collapsed lensed fiber.The extinction ratio ...
RZ-to-NRZ and NRZ-to-PRZ Format Conversions using a Photonic Crystal Fiber Based Mach-Zehnder Interferometer
Fiber properties Optical communications
2015/6/5
We have fabricated a photonic crystal fiber based Mach-Zehnder interferometer and demonstrated its use in both RZ-to-NRZ and NRZ-to-PRZ pulse format conversions for 10-Gb/s OOK signals.The PCF length ...
Tunable Free Space Optical Delay Interferometer for Demodulation of Differential Phase Shift Keying Signals
Phase modulation Interferometry
2015/6/4
With a continuously tunable free space optical delay interferometer and direct detection D(Q)PSK signals can be received at varying symbol rates or under optimized conditions. The in-terferometer’s ph...
An optical microfiber Sagnac interferometer with adjustable transmission
Fiber optics Microstructure device
2015/6/4
A Sagnac interferometer based on an optical microfiber is demonstrated. It shows good adjustability of transmission, which enables it to be used as linear edge filter, optical variable attenuator, or ...
Ring-coupled Mach–Zehnder interferometer optimized for sensing
Ring-coupled Mach–Zehnder interferometer optimized sensing
2015/8/10
We demonstrate numerically that the theoretical maximum sensitivity of a ring-coupled Mach–Zehnder interferometer (MZI) optimized as a sensor is about 30% greater than the optimized sensitivity of a c...
Characterization of Programmable Phase Modulator with Polarization Quadrature Interferometer
