Abstract: An optical transmitter particularly suited for high frequency applications s disclosed. The optical transmitter successfully operates in harsh environments such as those found in avionic applications. The optical transmitter employs an LED as a light source which cooperates with an active bandpass amplifier to provide a relatively wide bandwidth from about 250 MHz to about at least 1.35 GHz. The bandpass amplifier is selected to have a slope characteristic which is complementary to a roll-off characteristic of the LED and compensates for the high frequency loss of the LED. The slope characteristic of the bandpass amplifier predominates at the high frequencies of the response of the optical transmitter, whereas the frequency response of the LED dominates at the lower frequencies of the response.

Abstract: This invention relates to acrylic polymers and more specifically to polyalamides and polyacrylates such as poly{2-[(N-2-methyl-5-nitrophenylamino)ethyl acrylate]} and poly[(N-2-methyl-4-nitrophenyl)acrylamide]. These acrylic polymers are particularly useful as nonlinear optical components in various electrical devices for processing optical amplifiers, generators, computational devices and the like.

Abstract: A method is provided for decoding an input data stream formed of data words aving word boundaries and a synchronization word in a network interface unit of a high speed computer network. The input data stream is applied to a serial-to-parallel shift register to provide parallel boundary determination words for locating a word boundary within the data stream. There no serial shifting of bits within the parallel boundary determination words. The parallel boundary determination words are shifted through a register file in parallel and applied to synchronization word detectors which provide a series of detecting windows shifted from each other by one bit. When one of the word detection windows detects the synchronization word a word boundary is determined in accordance with the detection. Boundary detection data is thus effectively monitored in serial while it is shifted through the register file in parallel. This permits the use of slower and smaller logic in the register file.
