Custom Integrated Optics Devices


IonEx Custom Devices



For more than 18 years, Teem has expanded its expertise and capabilities in the domain of integrated optics circuits and systems through in-house developments and research collaborations. Today, Teem propose a large portfolio of optical functions and waveguide features (mode size, operating wavelength, interaction with glass surface,…) that can be combined by design or chip assembly to perfectly fit our custom client requests. We also propose pigtailing and packaging capabilities to hasten the development process of our clients.
