Prostate tumors are graded by the revised Gleason Score (GS) which is the sum of the two predominant Gleason grades present ranging from 6–10. GS 6 cancer exclusively with Gleason grade 3 is designated as low grade (LG) and correlates with better clinical prognosis for patients. GS >7 cancer with at least one of the Gleason grades 4 and 5 is designated as HG indicate worse prognosis for patients...
We demonstrate simple and wide carrier frequency offset compensation in CO-OFDM systems. The proposed method compensates CFO in the full-range as the sampling frequency. Using this method, we show PDM CO-OFDM-16QAM transmission over 1,600 km of standard single mode fiber.
ITER will explore a plasma parameter envelope currently not available in tokamaks. This will require a set of diagnostics that can follow this envelope. To implement these diagnostics in a reliable and robust way requires development of current techniques in many areas to make them applicable to ITER: they need to be operable in the ITER environment and satisfy the physics and engineering requirements...
We demonstrate novel detuned dual-mode laser for tunable continuous-wave terahertz generation with InGaAs-based photomixers. The beat frequency from this dual-mode multisection laser is continuously tuned from 0.30 to over 1.15 THz.
Genetically targeted neurons in brain expressing light sensitive channel Channelrhodopsin can be stimulated optically. We report a novel optical waveguide probe for simultaneous optical stimulation and electrical recording of neurons to modulate neural network behavior.
Micro air cavity fiber Mach-Zehnder interferometer (MZI) was experimentally demonstrated by femtosecond laser micromachining process followed by optimal fusion-splicing. Two optical paths were provided by the cavity to result in a characteristic, wide spacing MZI spectra.
Evolving technology and increasing pin-bandwidth motivate the use of high-radix routers to reduce the diameter, latency, and cost of interconnection networks. High-radix networks, however, require longer cables than their low-radix counterparts. Because cables dominate network cost, the number of cables, and particularly the number of long, global cables should be minimized to realize an efficient...
We have developed the first bi-directional ONT transceiver module having 10Gbit/s-Rx and 1.25Gbit/s-Tx for asymmetric high-speed TDM-PON, and have confirmed the 10Gbit/s downstream performance with the bi-directional transmission to support 128-way split and 10km reach.
We propose a tunable spectral bandpass filter using short- and long-wavelength bend-loss edges of both MSF and HOF. Various spectral functionalities of filter are obtained by carefully choosing optimal bend radii for serially concatenated fibers.
A balanced optical-RF phase detector for the extraction of low-jitter RF-signals from optical pulse trains, which is robust against drifts and photodetector nonlinearities, is presented. Sub-10 fs in-loop relative timing jitter is demonstrated.
We report a 4x4 HPCF coupler, HPCF pigtailed VCSEL and PIN PD with a low insertion loss and coupling loss, which can be readily applied in high speed short reach PON.
We demonstrate 314 W continuous-wave output power at 1077 nm from a Yb-doped fiber laser with a truly single-mode core. The core employed a W-type refractive index profile that suppressed detrimental stimulated Raman scattering through spectral filtering.
