Openings

We are looking for highly motivated postdocs and graduate students with interests in material processing, nanostructure fabrications, optical microscopy, electrodynamics and optoelectronics characterizations.

Potential research topics include, but not limited to:

I. Optical materials and their applications

• Semiconducting materials and their applications for optoelectronic devices (e.g., LEDs, laser diodes, photodiodes, solar cells, PICs)

• Optical metamaterials and their applications for flat optics (e.g., flat lens, polarimetry, hologram, mode converters, vortex generators)

• Atomically thin materials and their applications for polariton photonics (e.g., optical modulations, optical transistors, optical computing)

II. Design and fabrication of optical structures 

• 3D additive manufacturing of nanoparticles for generating on-demand 3D nanostructured materials in optical scale

• Inverse design of optical modes in nanostructured thin films and their applications for spatial light modulations within photonics platforms

• Seamless integration of optical materials onto CMOS-based electronics and their applications for photonic integrated circuits on CMOS

III. Electrodynamics and optoelectronics in optical materials

• Microscopy of light transport and optoelectronic conversions (e.g., hyperspectral imaging, photoluminescence, electroluminescence, near-field measurements)

• Spectroscopy of linear and nonlinear processes (e.g., saturable absorptions, harmonics generations, pump-probe measurements)

• Simulation of optical modes and their electrodynamics (e.g., finite-difference time-domain analysis, finite-element method, transfer matrix method) 

Prior experience in semiconductor fabrication, nanoparticle synthesis, optical measurements, electrodynamics simulations, and/or computer programming is desirable but not necessary.
