Welcome to San Francisco, California and the 25th IEEE Photonics Conference (previously known as the IEEE LEOS Annual Meeting). Following in the path of previous successful meetings, this year's conference features an extensive range of technical activities in addition to some unique events.
chapter
We present the first experimental demonstration of a novel class of hybrid III–V on silicon microlasers. This new type of laser revolves around the concept of resonant mirrors: two silicon cavities, directly coupled to the III–V laser mesa, provide high, narrow band reflection over a short distance. This results in a device that measures only 55 µm by 2µm and shows single-mode laser emission with...
chapter
We demonstrate a 1-Tb/s dual-carrier PDM-16QAM interface (all-electronic 80-GBaud per subcarrier). We transmit five dual-carrier channels over 3200 km at 5.2-b/sHz spectral efficiency, implementing coherent detection, off-line digital signal processing, and soft-decision forward error correction.
chapter
We report a directly modulated 850nm VCSEL-based Optical link operating at 55Gb/s. This is the highest modulation rate for VCSEL-based link of any wavelength.

As the current handling - bandwidth product of a single photodiode comprised of lattice matched In0.53Ga0.47As / InP material reaches a practical limit, we explore new lattice mismatched material system of In0.72Ga0.28As / InAsP / InP as a path-forward technology to increase this key parameter.

chapter
Demonstration of high-speed second harmonic holographic microscopic imaging of biological specimens up to 1500 volumes per second with signal-to-noise analysis and 3D particle tracking. Additionally, SHG holography phase-shifted reconstruction and polarization-resolved imaging are developed.
chapter
Abstract: We demonstrate a cost-effective and efficient approach for realizing ultrafast time-stretch microscopy in 1µm using the standard telecommunication single-mode fibers (e.g. SMF28 and dispersion compensation fiber (DCF)) as few-mode fibers (FMFs).
chapter
Different degrees of bacterial attachment to various surface morphologies observed by Hyperspectral Imaging Method are studied. Fore-ground and back-ground distinction performed by Singular Value Decomposition and Principal Component Analysis is also discussed.
chapter
Experimental and simulational validation of theory developed for diffraction and defocus effects on a novel single-pixel method that encodes spatial information using chirped amplitude modulation are presented.
chapter
We generate 10 GHz microwave signals from high quality factor (Q∼1011) optical resonators via optical frequency division. The demonstrated phase noise is comparable to or better than that obtained via cryogenic systems for timescales < 1s.
chapter
A tunable optoelectronic oscillator using a high finesse etalon as both a photonic filter and optical frequency reference is presented. The microwave tone at 10.487 GHz displays fractional frequency instability of 3.3×10−10 at 1 s.
chapter
The time-varying nature of optical pulses produces correlations in the photocurrent shot noise spectrum. These correlations are exploited to produce a phase noise floor of −177 dBc/Hz on a 10 GHz photonically generated microwave signal.
chapter
We describe a dual-frequency dual-polarization class-A vertical external-cavity semiconductor laser delivering a tunable optically-carried microwave signal with an additive phase noise below −120 dBc/Hz at 10 kHz.
chapter
The transient response of a directly modulated injection-locked semiconductor laser operated in the period-one state is analyzed theoretically and verified experimentally. The results illustrate the limits and stability properties of the modulated microwave subcarrier frequency.
