Modal field converter for a highly efficient coupling in optical modules |
摘要 |
An optical module (<HIL><PDAT>1</BOLD><PDAT>) which contains at least one optical component (<HIL><PDAT>2</BOLD><PDAT>) whose one optical input/output is directed towards an optical fiber (<HIL><PDAT>4</BOLD><PDAT>) to which it is to be coupled. At least one additional optical waveguide (<HIL><PDAT>6</BOLD><PDAT>) is arranged between this optical component (<HIL><PDAT>2</BOLD><PDAT>) and the optical fiber (<HIL><PDAT>4</BOLD><PDAT>). The optical component (<HIL><PDAT>2</BOLD><PDAT>) is provided with an optical waveguide (<HIL><PDAT>3</BOLD><PDAT>) whose end (<HIL><PDAT>5</BOLD><PDAT>), facing towards the optical fiber (<HIL><PDAT>4</BOLD><PDAT>), is tapered or widened for a modal field adaptation. Additionally the end of each interposed optical waveguide (<HIL><PDAT>6</BOLD><PDAT>) facing towards the optical fiber (<HIL><PDAT>4</BOLD><PDAT>) is also tapered or widened for a modal field adaptation.</PTEXT>
