The grant provides funding to upgrade the existing scattering-type scanning near-field optical microscope (s-SNOM) and nano-FTIR metrology suite present in his laboratory at Vanderbilt University to enable s-SNOM mapping into the telecom, mid-wave, and far-infrared (FIR) spectral ranges, perform s-SNOM and nano-FTIR measurements under applied electrical bias, and within transmission configurations. Specifically, this would provide four major upgrades:\u00a0<strong>1) Extend the spectral range for s-SNOM measurements via an optical parametric oscillator (OPO)-based laser, which provides excitation between 1.4-2.02, 2.25-4.45, and 5-18 \u00b5m free-space wavelengths. 2) Enable single point spectroscopy mode, providing IR spectra over the same spectral range as the OPO, effectively extending the range of Nano-FTIR to include the NIR and FIR. 3) Addition of photocurrent electrical testing attachment. 4) Enable s-SNOM and nano-FTIR measurements in transmission mode.<\/strong><\/p>\n<p>The proposed instrumentation is designed to meet the challenges of current and future DoD programs, with PI Caldwell\u2019s recently funded ONR MURI program a specific focus. This program aims to understand the role of crystal structure and symmetry in driving hybridization and strong coupling phenomena within moir\u00e9 and twist-optic structures. These offer opportunities for active beam-steering and tuning of emitters, novel laser and electro-optic devices, polarization control including dictating chirality, and nonlinear optical responses within the IR. The expanded functionality will benefit a variety of DoD programs, including those at the Naval Research Laboratory and multiple universities including Vanderbilt, Penn State, Stanford, University of Minnesota, University of Iowa, and University of Virginia.<\/p>\n<p><a href=\"https:\/\/www.defense.gov\/News\/Releases\/Release\/Article\/3615077\/dod-awards-161-million-to-universities-to-purchase-equipment-supporting-defense\/\">https:\/\/www.defense.gov\/News\/Releases\/Release\/Article\/3615077\/dod-awards-161-million-to-universities-to-purchase-equipment-supporting-defense\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Caldwell group was recently awarded an FY24 Defense University Research Instrumentation Program grant to purchase several upgrades to the nano-optic probes housed within the laboratory.
