In this paper, we demonstrate experimental alloptical code-division multiplexing (AO-CDM) systems using 64-ps optical pulses and a 2n prime code of n = 3. A distinguishing feature of this experiment is that the modulation of ultrashort optical clock stream by electrical data is realized without using any optical intensity modulator at each transmitter. Moreover, only low-cost standard optical 2...

Optical Coherence Tomography (OCT) is an emerging optical imaging technology with ever growing number of applications. OCT enables micron scale cross-sectional imaging of subsurface microstructures by measuring the backscattered intensity of light from subsurface layers of the materials. Current OCT imaging systems are fiber or free space optics based and they can be miniaturized through integr...

Supercontinuum generation (SCG) in a tapered chalcogenide fiber is desirable for broadening mid-infrared (or mid-IR, roughly the 2-20 μm wavelength range) frequency combs(1, 2) for applications such as molecular fingerprinting, (3) trace gas detection, (4) laser-driven particle acceleration, (5) and x-ray production via high harmonic generation. (6) Achieving efficient SCG in a tapered optical ...

Optocouplers offer tremendous advantages in minimizing EMI and noise susceptibility. It is not an exaggeration to say that a healthy sprinkling of opto-isolation has often meant the difference between a “good idea” and working product. Yet, these very useful devices are often overlooked as possible solutions in designs because they are perceived to be “slow”. It is true that there are some limi...
