Rack Mountable Soliton Microcomb with Turn-Key operation for Scientific and Industrial Applications

Project description

A new generation of optical frequency comb technology heads to market

Optical frequency combs are like rulers that enable us to measure the exact frequencies of light, from invisible infrared and ultraviolet to visible blue light. Aside from optical atomic clocks, the ability to ‘comb’ a sample based on absorption and reflection enables the identification of molecules in many fields, from astronomy and atmospheric science to medical diagnostics. Soliton microcombs are the next generation with several important improvements over the current state of the art. However, there is no market-ready product available for scientific and industrial applications. The EU-funded RaMSoM project is planning to deliver the first such device and demonstrate its capabilities in the field.


"The invention of the optical frequency comb (OFC) has enabled counting of optical frequencies and has thereby given rise to optical atomic clocks that today are even sensitive to the gravitational redshift and are of crucial importance for future improvements to navigation, positioning, and timing. The early generation of OFC based on mode-locked lasers are already commercially available but suffer from a number of limitations in terms of system size and complexity, and notably, low attainable repetition rates (<10 GHz). However, higher repetition rates (>10 GHz) are essential in many applications. The discovery of microresonator-based Kerr frequency combs (microcombs) has revolutionized the field and paved a route to a compact OFC, with broad optical bandwidth and repetition rates in the microwave to terahertz domain (10 GHz - 1 THz). Despite such undeniable advantages of soliton microcombs over other types of OFCs as chip-scale footprint and unique combination of high repetition rates and broad bandwidth reaching an octave, there is however no commercial product that would expose the soliton microcomb technology to the market and offer an optical frequency comb with similar performance and scale.
The focus of the RaMSoM project is to design and build the world's first 19""-rack-mounted stand-alone soliton microcomb source with the turn-key operation and demonstrate its performance and reliability in scientific and industrial applications. The project will pursue the following objectives: (1) development of a turn-key reliable soliton microcomb source in a 19""-rack chassis; (2) employment of the developed stand-alone system for novel scientific applications, including multi-wavelength broadband spectroscopy and neuromorphic optical computing; (3) development of an industrial-grade soliton microcomb system with enhanced tuning functionality and demonstration of field applications in cooperation with industrial partners.
