Abstract
Aluminized optical fiber is used for transmitting electricity, as well as transmitting lightwaves. In one example, an aluminized optical fiber (17) is bonded within a photonics package in contact with a conductor (15) that interconnects it to a photonic device (12) or electronic circuit. Power is then supplied to the package by applying it to the aluminized coating (19) of the optical fiber. This avoids the need for a separate conductor extending into the photonics package for supplying electrical power. It also may significantly simplify system design since the power supply can conveniently be included a fairly remote distance from the photonics package. The aluminized optical fiber can be bonded to a metallization in the V-groove (13) that provides electrical contact simply by applying heat and pressure. This allows the aluminized fiber to be bonded without the need for any adhesives, while assuring good electrical contact for the transmission of electrical power. According to another embodiment (FIG. 6 ), the aluminized coating is used for electrical communication in an optical fiber television system.
