Corey Loke

Opto-Mechanical Engineer

Bio

Corey is an accomplished opto-mechanical engineer specializing in optical systems optimization and precision engineering. Currently Co-Founder and Partner at Arcsecond Labs LLC, he previously served as Staff Opto-Mechanical Engineer at Resolve Biosciences, developing dual-camera fluorescence microscopes for spatial multi-omics applications. At Quantum-Si, he was the main opto-mechanical engineer on the Optical Devices Team, leading all opto-mechanical component design and manufacturing, scaling the laser system, and building inspection and alignment tools that improved manufacturing yield and system reliability. His earlier work at ASML focused on particle defectivity analysis for semiconductor manufacturing and leading optical alignments for photolithography systems, with research published in SPIE.

Corey holds a degree in mechanical engineering from Fairfield University and excels in product design, manufacturing processes, and precision alignments. He also serves as Lead Design Engineer at Horological Works LLC, where he earned US Patent 11,442,408 for a novel double escapement mechanism. Known for his technical leadership, he consistently delivers innovative solutions in complex engineering environments.

Michael A. Bellos PhD

Optical Engineer

Bio

Michael is a highly accomplished optical engineer and physicist specializing in laser technology and microscopy. Currently Co-Founder and Partner at Arcsecond Labs LLC, he spent the past decade at biotech startups including Quantum-Si, where he led the Optical Devices Team in developing next-generation protein sequencing technology, established manufacturing lines in Asia and the US, and improved system reliability tenfold—contributions that helped drive the company’s successful 2021 IPO. His earlier work at Coherent Inc. produced the first commercially available high-power carbon monoxide laser operating at 5 microns.

Michael holds a PhD in Physics from the University of Connecticut and completed postdoctoral research at Yale University in experimental Atomic, Molecular, and Optical Physics. He holds multiple patents in laser and optical technologies and has published groundbreaking research in Science. Bilingual in English and French, he continues to advance optical engineering through his work at Arcsecond Labs.

Faisal R. Ahmad

Systems Engineer

Bio

Faisal is an accomplished physicist and technology leader with over two decades of experience in semiconductor devices, optoelectronics, and laser systems. Currently Co-Founder and Partner at Arcsecond Labs LLC, he works with a team in designing advanced optical systems including laser construction, custom microscopes, and optical metrology tools. As founding member of the Optical Devices Team at Quantum-Si, he designed and built prototypes of the pulsed laser system for their protein sequencing platform, established production lines in Asia and the US, and developed manufacturing instruments including a novel saturable absorber quality control apparatus—work that was cornerstone to the company’s successful 2021 IPO. His career also includes leadership roles at Resolve Biosciences, Detect, and General Electric Company. Faisal holds a PhD in Physics from Cornell University, where he researched ultrashort pulse generation from semiconductor mode-locked lasers, and a BSc in Theoretical Physics from Imperial College London. His combination of theoretical understanding and practical implementation has established him as a respected leader in optical and laser technologies. He is fluent in English, Urdu, and German.
