Photonic Jet, a new laser technology for sub-µm processing of different materials
A German company offers a fibre based laser technology - so called Photonic Jet Technology -, which allows to process extraordinarily small areas. This is realised by using infrared nanosecond lasers in combination with optical fibres including integrated optics. Successful material processing of different semiconductors and metals is already done. The company is looking for a commercial agreement with technical assistance.
German SME is looking for companies, preferably SME, which need a laser technology for processing or marking (e.g. semiconductors or metals) with sub-µm resolution. Possible applications of this technology could be, for example, in the fields of microelectronics, analysis, biotechnology or medical technology.
A German company is looking for companies, preferably SME, which need a laser technology for processing or marking (e.g. semiconductors or metals) with sub-µm resolution. The new Photonic Jet Technology is a laser technology using optical fibres including integrated optics for delivery and focussing of the laser beam. Therefore, no additional focussing optics is required. This technology allows the processing of extremely small areas on the sample surface. The diameters of laser-generated features are below 1 µm. Photonic Jet produces: Features with sub-µm diameter: 0.4 ... 0.9 µm, By using IR-ns-Laser: 1064 nm, 0.5 ... 100 ns and a multimode fibre: e.g. 200 µm diameter. Successful material processing of silicon, stainless steel, copper, gold, silver, titanium, ITO is already done. Possible applications of Photonic Jet Technology are: - Sub-µm marking (dot, line) - Semiconductor processing - Bio-medical sample processing or preparation - Generation of electronic functionalities - Thin film processing - 3D-machining below 10 µm - Local thin film deposition Commercial users are sought which need to generate features with sub-µm diameter on special samples. This could be for instance the generation of markings on semiconductor chips or the cutting of ultra-thin films or of small biological samples. A commercial agreement is requested.
Advantages and innovations
To date, very complex and expensive photolithographic processes or cost-intensive laser systems with ultrashort pulse durations in the range of femtoseconds are needed to produce such small structures. In contrast, the Photonic Jet works with low cost lasers delivering comparatively long pulses in the nanosecond range.

How it works
- Tell us about yourself
- We’ll discuss with you
- We put the right partners in touch
EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
First we need to check you’re human.
