| 1 | Ultrahigh frame rate digital light projector using chip-scale LED-on-CMOS technology显示文摘Digital light projector systems are crucial components in applications,including computational imaging,fluorescence microscopy,and highly parallel data communications.Current technology based on digital micromirror displays are limited to absolute frame rates in the few tens of kiloframes per second and require the use of external light sources and coupling optics.Furthermore,to realize gray-scale pixel values using duty cycle control,frame rates are reduced proportionally to the number of gray levels required.Here we present a self-emissive chip-scale projector system based on micro-LED pixels directly bonded to a smart pixel CMOS drive chip.The 128×128 pixel array can project binary patterns at up to 0.5 Mfps and toggle between two stored frames at megahertz rates.The projector has a 5-bit gray-scale resolution that can be updated at up to 83 kfps,and can be held in memory as a constant bias for the binary pattern projection.Additionally,the projector can be operated in a pulsed mode,with individual pixels emitting pulses down to a few nanoseconds in duration.Again,this mode can be used in conjunction with the high-speed spatial pattern projection.As a demonstration of the data throughput achievable with this system,we present an optical camera communications application,exhibiting data rates of>5 Gb/s. | NAVID BANI HASSAN FAHIMEH DEHKHODA ENYUAN XIE JOHANNES HERRNSDORF MICHAEL J.STRAIN ROBERT HENDERSON MARTIN D.DAWSON | 2022 | Photonics Research2022，10，10： | 1 |
| 2 | All-optical tuning of a diamond micro-disk resonator on silicon显示文摘High-quality integrated diamond photonic devices have previously been demonstrated in applications from nonlinear photonics to on-chip quantum optics.However,the small sample sizes of single crystal material available,and the difficulty in tuning its optical properties,are barriers to the scaling of these technologies.Both of these issues can be addressed by integrating micrometer-scale diamond devices onto host photonic integrated circuits using a highly accurate micro-assembly method.In this work a diamond micro-disk resonator is integrated with a standard single-mode silicon-on-insulator waveguide,exhibiting an average loaded Q-factor of 3.1×10^4 across a range of spatial modes,with a maximum loaded Q-factor of 1.05×10^5.The micrometer-scale device size and high thermal impedance of the silica interface layer allow for significant thermal loading and continuous resonant wavelength tuning across a 450 pm range using a milliwatt-level optical pump.This diamond-on-demand integration technique paves the way for tunable devices coupled across large-scale photonic circuits. | PAUL HILL CHARALAMBOS KLITIS BENOIT GUILHABERT MARC SOREL ERDAN GU MARTIN D.DAWSON MICHAEL J.STRAIN | 2020 | Photonics Research2020，8，3： | 0 |
| 3 | Passive mode-locking in semiconductor lasers with saturable absorbers bandgap shifted through quantum well intermixing显示文摘Passive mode-locking in semiconductor lasers in a Fabry–Perot configuration with a bandgap blueshift applied to the saturable absorber(SA)section has been experimentally characterized.For the first time a fully post-growth technique,quantum well intermixing,was adopted to modify the material bandgap in the SA section.The measurements showed not only an expected narrowing of the pulse width but also a significant expansion of the range of bias conditions generating a stable train of optical pulses.Moreover,the pulses from lasers with bandgap shifted absorbers presented reduced chirp and increased peak power with respect to the nonshifted case. | Vincenzo Pusino Michael J.Strain Marc Sorel | 2014 | Photonics Research2014，2，6： | 0 |
