A silicon photonic waveguide system with mode-division and wavelength-division-multiplexing capabilities is demonstrated. Error-free (BER < 10−12) data transmission of 2 modal channels and 3wavelengths operating with aggregate bandwidth of 60-Gb/s is realized. This work motivates future bandwidth scalability of silicon photonic interconnects.

Three multiplexing schemes are presented for polarization-maintaining photonic crystal fiber based Sagnac interferometric sensors. The first technique is wavelength division multiplexing using coarse wavelength division multiplexers (CWDMs) to distinguish signals from each multiplexed sensor in different wavelength channels. The other two schemes are to multiplex sensors in series along a singl...

We propose and demonstrate a new wavelength-division-sampling technique with high temporal resolution. A discrete-time true-time delay generates multiwavelength near-transform-limited pulses from a supercontinuum source. Pulses sample the analog signal in an electro-optic modulator and are subsequently demultiplexed in a wavelength-division-multiplexing filter. A 100-Gsample/s experimental demo...

We describe the transmission characteristics of a wavelength independent wavelength division multiplexing passive optical network (WDM-PON) based on a wavelength channel data rewriter (WCDR). The WCDR is composed of a linear amplifier (LA) and a saturated semiconductor optical amplifier (SOA), and by using the WCDR in optical network units (ONUs), we can erase the downstream signal and modulate...

Ramamurthy, Dhritiman Banerjee, and Jason Iness Department of Computer Science, University of California, Davis, CA 95616 Abstract Multiprocessor architectures based on optical interconnects employing wavelength division multiplexing (WDM) are considered. WDM is a technique used to divide the tremendous bandw...

The optical networks are fast and error free but due to some nonlinearity effects, its performance degrades. The performance of wavelength division multiplexing (WDM) in radio over fiber (RoF) systems is found to be strongly influenced by nonlinearity characteristics inside the fiber. In this paper, we have studied the effect of four wave mixing (FWM) as one of the influential factors in the WD...

In this paper we proposed the physical layer security scheme in WDM-PON. Simulated result of eavesdropping attempt in WDM-PON is presented. This physical security enhancement is accomplished through inclusion of Broadband Light Source in OLT to create a TDM signal in which each data frame is transmitted at unique wavelength. Simulation tools verify that implementation of enhance security techni...

Mode division multiplexing (MDM) is a promising technology for increasing the aggregate bandwidth of multimode fiber (MMF) in conjunction with wavelength division multiplexing (WDM) in face of the impending capacity crunch in optical fiber networks. This paper investigates the effect of radial and azimuthal mode spacings in a 25-channel MDM-WDM system in MMF using a spatial light modulator-cont...

An optical fiber sensor network for ultrasonic measurement based on wavelength division multiplexing (WDM) and time division multiplexing (TDM) technology is presented. Each of the sensor probes is an optical fiber extrinsic Fabry-Perot interferometer (EFPI) which is composed of the fiber’s end face and the aluminum thin diaphragm. The sensors are arranged in different wavelength domains formed...
