The photonic integrated circuit (PIC) can perform one-dimensional spectroscopy of unique input spectra using a single baseline within its 91 available baselines. The PIC uses polarization-diversifying gratings to separate incoming light into two distinct polarizations, an on-chip 2 \u00d7 4 optical hybrid, and a strong local oscillator (LO) to perform the heterodyne measurements. The optical hybrids combine the input signals with the LO and split them into two component pairs for phase-sensitive measurements. Furthermore, the PIC can perform 2D image reconstruction by combining many baseline pairs to measure the visibility of a simple target. These demonstrations show the PIC\u2019s capabilities for 1D spectroscopy and 2D imaging applications.<\/jats:p>","DOI":"10.1021\/acsphotonics.6c00631","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T18:02:18Z","timestamp":1788976938000},"page":"5554-5562","source":"Crossref","is-referenced-by-count":0,"title":["Silicon Photonics-Based\nHeterodyne Interferometric\nImager for Free-Space Imaging"],"prefix":"10.1021","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-4047-4739","authenticated-orcid":true,"given":"Humphry","family":"Chen","sequence":"first","affiliation":[{"name":"Lockheed Martin , , 3251 Hanover St. , , ,","place":["Palo Alto, California, United States, 94304"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingye","family":"Fu","sequence":"additional","affiliation":[{"name":"University of California Davis , , One Shields Ave , , ,","place":["Davis, California, United States, 95616"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shun-Hung","family":"Lee","sequence":"additional","affiliation":[{"name":"University of California Davis , , One Shields Ave , , ,","place":["Davis, California, United States, 95616"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shelbe","family":"Timothy","sequence":"additional","affiliation":[{"name":"Lockheed Martin , , 3251 Hanover St. , , ,","place":["Palo Alto, California, United States, 94304"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lawrence","family":"Shing","sequence":"additional","affiliation":[{"name":"Lockheed Martin , , 3251 Hanover St. , , ,","place":["Palo Alto, California, United States, 94304"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gopal","family":"Vasudevan","sequence":"additional","affiliation":[{"name":"Lockheed Martin , , 3251 Hanover St. , , ,","place":["Palo Alto, California, United States, 94304"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tony","family":"Kowalczyk","sequence":"additional","affiliation":[{"name":"Lockheed Martin , , 3251 Hanover St. , , ,","place":["Palo Alto, California, United States, 94304"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neal","family":"Hurlburt","sequence":"additional","affiliation":[{"name":"Lockheed Martin , , 3251 Hanover St. , , ,","place":["Palo Alto, California, United States, 94304"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Joo Ben","family":"Yoo","sequence":"additional","affiliation":[{"name":"University of California Davis , , One Shields Ave , , ,","place":["Davis, California, United States, 95616"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"2026100710080667400_cit1","doi-asserted-by":"publisher","first-page":"172","DOI":"10.1007\/s11207-020-01736-7","article-title":"The Daniel K.
