Background

About Daniel Mrena

Photonic Engineer | Laser Interference Lithography | Nanotechnology | Startup Founder I am a researcher, photonic engineer, and startup founder specializing in laser-based nanofabrication and optical detection technologies. My expertise spans laser interference lithography (LIL), diffractive optics, and long-range detection of chemical warfare agents (CWA) and toxic industrial chemicals (TICs). As part of my PhD research, I explore how LIL and direct laser writing can be combined to fabricate complex periodic and aperiodic structures with precise control over symmetry and periodicity. This work has direct applications in optical devices, biosensing, and metamaterials. In parallel, I work in R&D as an optoelectronic engineer, focusing on advanced detection systems for hazardous chemicals using cutting-edge optical sensing technologies. Additionally, I co-founded a startup that brings compact tabletop laser interference lithography tools to researchers and industry professionals. Our mission is to make high-quality, customizable diffraction gratings and holographic structures more accessible for cutting-edge applications. Key Areas of Expertise: Laser Interference Lithography (LIL) Diffractive & Holographic Gratings Micro- & Nanofabrication Optical Detection of CWA & TICs Optical Characterization (SEM, AFM, Spectroscopy) Scientific Writing & Research Publications Startup Development & Tech Commercialization I’m always open to discussions on collaborations, research opportunities, and innovative applications of laser-based nanofabrication and optical sensing.
