2016 Optical Fiber Communication Conference   unpublished
A WS-TDMA optical switch fabric scalable to 1024 ports is demonstrated.  ...  Thus an ideal future switch for data centers has a large port count (>1000 ports) with a high per-port bitrate (>10Gb/s), providing consistently low latency whilst being able to flexibly share a large  ...  Conclusions A 1024 port optical switch data plane combining wavelength switching and TDMA over a passive fibre star coupler for packet level reconfigurability has been demonstrated.  ...

RF Mixers [chapter]

2010 Radio Frequency Circuit Design  
ACKNOWLEDGMENT The authors wish to acknowledge the help of Terry Jamison in the analysis of the impulse response data.  ...  Hybrid capacitors are available in both single-layer capacitors for high-frequency low-capacitance applications and multi-layer capacitors for higher capacitance.  ...  This will make the transistor act more like a switch with the attendant high efficiency.  ...

2013 International Journal of Emerging Trends in Electrical and Electronics (IJETEE)   unpublished
In this paper a modified Canny Algorithm has been proposed which uses variable sigma for different parts of the image.  ...  In our experiment, an optical spectrum analyzer is connected to the output port of the second coupler for wavelength characterization of the amplifier.  ...  Part B is used for input through optoisolater, Port D for MAX 485 output. Port C for output Relay driver.  ...
