LOLIPOP

​The EU-funded LOLIPOP project builds on TriPleX, a proprietary waveguide technology for photonic integrated circuits developed by Netherlands-based company LioniX International which satisfies the growing need for bandwidth and capacity in telecommunication and sensing applications. LOLIPOP will focus on equipping TriPleX with new functionalities by exploring materials like: lithium niobate on insulator (LNOI), an excellent material for high-speed light modulation; germanium, known for its high-speed and ultra-wide bandwidth detection capabilities; and gallium arsenide, a well-established material for gain chips. To combine LNOI and TriPleX, various hybrid integration methods, such as flip-chipping and micro-transfer printing, will be explored. For the germanium photodiodes, heterogeneous integration will be developed to achieve high detection efficiency in a broad wavelength range (400–1 600 nm).
