A fiber for use in an optical communications system has a core of mainly fused quartz glass of high purity having uniform refractive index in section, and an organic material coated around the outer periphery of said core and having a lower refractive index than that of said core. By ...
compoundsemiconductor materialscannot offer clean sharp edges for gating photons in optical signals. This scenario is similar to the delayed impact of semiconductordigital computersof the mid-1950s onswitching systemsof the mid-1960s. Having its inception in 1948 (Telephone Laboratories, 1982), the ...

This paper presents a novel optical communication technique that provides a second, low data channel on an existing high-speed fiber optic link. The second channel is derived using an acousto optic fiber phase modulator and interferometric receiver. This method modulates the optical phase of the ori...
