Patent ID: 6956995

Claim:
An optical communication arrangement comprising: a. an optical coupler comprising a first refraction surface having a first finite focal length, a second refraction surface having a second finite focal length, and an internal reflector such that in operation a first optical signal enters the first refraction surface, couples from the first refraction surface to the second refraction surface via the internal reflector, and exits the second refraction surface, the first optical signal thereby defining a light path; b. an opto-electronic component optically coupled to the light path of the optical coupler; and c. an optical fiber optically coupled to the light path of the optical coupler; wherein: i. the opto-electronic component comprises a vertical cavity surface emitting laser, the opto-electronic component optically couples to the first refraction surface of the optical coupler; ii. the optical fiber optically couples to the second refraction surface of the optical coupler; iii. the first optical signal couples from the opto-electronic component to the optical fiber via the optical coupler; iv. a second optical signal couples from the optical fiber to the second refraction surface, couples from the second refraction surface to the first refraction surface via the internal reflector, and couples from the first refraction surface to the opto-electronic component; and v. the opto-electronic component further comprises a transceiver, the transceiver comprising the vertical cavity surface emitting laser and a photo-diode.
