Abstract
An optical transceiver system includes a transmitter emitting a first light beam having a first wavelength, a receiver receiving a second light beam having a second wavelength; an optical fiber transmitting the first light beam and the second light beam; and a light guide member. The light guide member includes a lens block having a bottom surface facing toward both the transmitter and the receiver, a first side surface slanted relative to the bottom surface, and a second side surface facing toward the optical fiber, a first lens and a second lens formed on the bottom surface for optically coupled with the respective transmitter and receiver, a third lens formed on the second side surface for optically coupled with the optical fiber, and a light guide portion embedded in the lens block.
Claims12
An optical transceiver system comprising:
- a transmitter configured for emitting a first light beam having a first wavelength;
- a receiver configured for receiving a second light beam having a second wavelength;
- an optical fiber configured for transmitting the first light beam and the second light beam;
- and
- a light guide member comprising:
- a lens block comprising a bottom surface facing toward both the transmitter and the receiver, a first side surface slanted relative to the bottom surface, and a second side surface facing toward the optical fiber,
- a first lens formed on the bottom surface and optically coupled with the transmitter;
- a second lens formed on the bottom surface and optically coupled with the receiver;
- and
- a third lens formed on the second side surface and optically coupled with the optical fiber;
- and
- a light guide portion embedded in the lens block and perpendicular to the bottom surface and obliquely oriented relative to the second side surface, the first side surface configured for reflecting first light beam from the transmitter, the light guide portion configured for guiding and directing the reflecting first light beam to the third lens, and guiding and directing the second light beam passing through the third lens to the first side surface, the first side surface further configured for reflecting and directing the second light beam to the second lens, wherein the index of refraction of the light guide portion is less than that of the lens block.
