A diffraction element diffracts the collimated light of the at least two wavelengths into different wavelength components. The reflector is moved so that one or more of the different wavelength components will be focused by the lens unit in the return path and detected. The second surface reflects the light of the at least two wavelengths from an input port towards the first convex surface and the first convex surface collimates the reflected light of the at least two wavelengths in the forward path, or the first convex surface focuses the one or more wavelength components towards the second surface that reflects the one or more wavelength components to an output port in the return path. The first convex surface can be replaced by a GRIN lens performing the focusing and collimating functions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tunable optical module for optical communication","description":"Light of at least two wavelengths is collimated in a forward path towards a reflector and light of at least one of the wavelengths is focused and detected in a return path, using in both paths a lens ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9660681","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
