Welcome to our Lab

Our laboratory is housed within the Knight Physics Building on the University of Miami's Coral Gables campus. It consists of two primary areas:

Office Space: Equipped with desks and computers for data analysis and research.
Laboratory: A fully isolated space with independent air conditioning to maintain precise temperature and humidity levels.

Laboratory Features:

Vibration Isolation: Two large optical tables with active vibration isolation legs, further isolated from the building's foundation to minimize disturbances, ideal for sensitive quantum interferometric experiments.
Experimental Capabilities: Our lab is equipped to perform nonlinear and quantum experiments, utilizing Spatial Light Modulators, pulse and CW lasers, Single photon detectors, power meters, power supplies, and optomechanics and more.

Some of the Equipment in the Lab:

Lasers Systems

Ultrafast Ti:Sapphire Lasers

The Mai Tai DeepSee laser with Automated Dispersion Compensation offers over 2.4 W of average power and 350 nm (690-1040 nm) in useable tuning range with the pulse width <70fs. Aplications: Bio-Imaging Two-Photon Fluorescence Microscopy (2PF), Second Harmonic Generation Microscopy (SHG), Multimodal microscopy, Terahertz imaging, Ultrafast Spectroscopy Time-resolved spectroscopy, Non-linear spectroscopy Semiconductor Metrology, Amplifier seeding

Single Frequency Laser Diode

The Ondax 405nm blue-violet wavelength stabilised laser is a miniature laser in a standard TO 5.6mm package. The wavelength stabilisation is achieved by optical feedback using the Ondax Volume Holographic Grating (VHG) PowerLocker, which ensures a stable single longitudinal mode operation.

Parameters: Coherence length >1m, collimated output beam, Output Power: 40 mW, Center Wavelength: 405 nm, Linewidth (MHz): 160 MHz

Helium-Neon Laser

Cylindrical red (632.8 nm) Helium-Neon lasers feature a tube design that makes them easy to mount in nearly any optical system. The HNL210LB outputs a 21.0 mW, linearly polarized beam that is polarized vertically with respect to the cable at the rear of the laser's housing. The HNL225RB model offers a 22.5 mW, fluctuating output polarization.

Quantum Detection Systems

Time Controller

IDQ - ID1000-TCSPC (time-correlated single-photon counting) offers time-tagging, counting and histogram correlation continuously on five interchangeable input & reference channels, ideal for all applications requiring time-resolved and picosecond-precise event tagging.

Silicon Avalanche Photodiode

The SPCM-AQ4C is a four-channel photon counting module capable of detecting single photons of light over the wavelength range from 400 nm to 1060 nm. Each channel is independent from the others.

The SPCM-AQ4C uses a unique silicon avalanche photodiode (SLiK) that has a circular active area of 180 μm diameter with a peak photon detection efficiency exceeding 60% at 650 nm

Spatial Light Modulators

Digital Micromirror Device (DMD)

DLP 0.3 WVGA Chipset The 0.3 WVGA Chipset is in the family of DLP Technology offered from TI and includes these two devices:: DLP3000—0.3 WVGA DMD and DLPC300—DLP3000 Digital Controller.

The DMD is an electrical input, optical output memory device. Each micromirror of the DMD can be individually defl ected about a hinged axis. The defl ection angle of each micromirror (±12°) .

Liquid Crystals Based SLM

Santec SLM 200 - is reflective LCOS (liquid crystal on silicon) is an advanced spatial light modulator for full high resolution applications. WUXGA (1920 x 1200) resolution, 10-bit (1024 gray levels) and excellent phase stability (~0.001π rad.) make ultra-fine light modulation possible for various applications.

Liquid Crystals Based SLM

The SDE1024 is a low-cost electrically-addressed liquid crystal spatial light modulator made by Cambridge Correlators. It contains a reflective LCOS (liquid crystal on silicon) display, which has a 62% reflectance at 633nm. The active area is 9.3x7mm with 1024x768 pixels (at 9x9μm each).
