In this paper, we propose techniques to design and fabricate polymer micro-cantilevers for attachment onto the end of standard single mode fibers using laser machining. The polymer cantilever is fabricated by laser micro-machining a sheet of polymer into the required shape and then bonded onto the top of a ceramic ferrule by photo resist as a flat supporting and bonding layer. The dimension of resulting...
New designs of bend-insensitive multimode fibers are proposed. The bending loss can be reduced by a factor of 10 while meeting all other standard requirements. The design concept is validated by actual fiber results.
OFDM has emerged as a promising modulation technique in long-haul and access optical networks. The computational complexity of the format can be met with powerful digital signal processors, and especially by exploiting all-optical signal processing.
112 Gb/s field trial demonstration of a complete ETDM system based on monolithically integrated transmitter and receiver modules was achieved for the first time, with BER performance below FEC error-free threshold at 231-1 PRBS tributary data word-length.
The discrete Fourier Transform (DFT) or its more popular efficient algorithm, the Fast Fourier Transform (FFT) is one of the important mathematical functions in the toolbox of signal processing. To this date its processing speed is limited by the underlying electronic processors. We show that FFT signal processing limitations can be overcome by performing the FFT in the optical domain and demonstrate...
OFDM data with line rates of 5.4 Tbit/s or 10.8 Tbit/s are generated and decoded with a new real-time all-optical FFT receiver. Each of 75 carriers of a comb source is encoded with 18 GBd QPSK or 16-QAM.
This paper reviews a technology for making nano-engineered optical fibers. Key features and advantages of nano-enginneered glass fibers are discussed. Fiber designs and their applications are presented.
An add/drop filter using a Bragg grating-assisted mismatched coupler is fabricated. The maximum reflectivity, 3dB bandwidth, insert loss at the drop port and reflective loss at the input port of the filter are measured to be about 12 dB, 0.2 nm, 3.91 dB and −7.39 dB, respectively.
This paper discusses stimulated Brillouin scattering (SBS) in optical fibers. Theoretical approach for analyzing the SBS in fiber is described. Different fiber design methods for reducing the SBS effect are presented
A new hole-assisted single polarization fiber is fabricated with extinction ratios as high as 60 dB in lengths smaller than 1 meter. The fiber contains a hole on each side of the core and on the minor axis.
