  2. Hui Cao Seminar

    Disordered Photonics Most of the research in the field of photonics has focused on understanding and mitigating the effects of disorder which are often detrimental. For certain applications, however, intentionally introducing disorder can actually improve the device performance, e.g., in photovoltaics optical scattering improves the efficiency of light harvesting. We have utilized multiple scattering in a random photonic structure to build a compact on-chip spectrometer. The probe signal...

  3. Abram Falk - Quantum Photonics Faculty Candidate Seminar

    Abram Falk Postdoctoral Fellow Institute for Molecular Engineering at Univeristy of Chicago   Engineered defects in wide band-gap semiconductors for single-spin sensing and computation While generally considered undesirable in traditional electronic devices, semiconductor defects can confine isolated electronic spins and act as nanoscale, single-spin memory registers. Alongside research efforts focusing on nitrogen-vacancy centers in diamond, an alternative approach seeks to...

  4. Needs Seminar - Dr. Shaloo Rakheja, Massachusetts Institute of Technology

    Abstract - With its rich physical properties, the novel 2-D carbon-based material graphene is expected to play an important role in the advancement of semiconductor technologies. In a recent poll conducted by the International Technology Roadmap for Semiconductors (ITRS), graphene is named as the material most likely to have the greatest impact on geometric scaling. As a two-dimensional material, graphene has a limited phase space for scattering of electrons; hence, the electrons in...

    Quantum Assisted Magnetometry with NV centers in Diamond Nitrogen vacancy (NV) color centers are point defects that occur naturally in diamond. They can also be created artificially via standard semiconductor fabrication techniques. Associated with this defect are spin states that can be initialized & read-out optically, and driven coherently with resonant microwaves. The coherence time of NV spins tends to be quite long even at room temperature. For these reasons, NVs are ideally...

  6. Sunil Bhave Seminar

    Optomechanical systems offer one of the most sensitive methods for detecting mechanical motion using shifts in the optical resonance frequency of the optomechanical resonator. Presently, these systems are used for measuring mechanical thermal noise displacement or mechanical motion actuated by optical forces. Meanwhile, electrostatic capacitive actuation and detection is the main transduction scheme used in RF MEMS resonators. The use of electrostatics is convenient as it allows direct...

  10. Igor Melnikov Seminar

    Aluminum Oxide as a Self-Organizing Template for Heterogeneous Photonic Crystals In this talk, heterogeneous photonic crystals are described that are made of group II-oxides, sulfides, and selenides electrochemically deposited in the template of a selforganizing porous aluminum oxide. The self-organization approach to nano-structured materials and templates looks like a much simpler and, hence cheaper technological alternative to lithography-based ones. The self-organization here might be...
