Abstract: A time to digital converter (TDC) is able to be utilized for measuring a time interval between two signals with a very fine time resolution, which is defined as the difference in propagation delay per stage between two rings or chains of delay stages. The Vernier ring TDC, Vernier TDC with comparator matrix or Vernier ring TDCs with comparator matrix comprise two rings or chains of delay stages with slightly different propagation delays per stage and a plurality of comparators for comparing two signals propagation along two rings or chains and determining when the lag signal passes the lead signal. The lead and lag signal are initiated by two events and are each fed into a separate one the first stages of one of the specified rings or chains. The comparators are able to be organized in a comparator matrix in order to occupy less space and permit reuse. As a result, the input time interval (the time between the two initiating events) is able to be measured through the product of the time resolution and the number of stages through which the two signals propagated.

Abstract: Methods and apparatus for providing improving optical signal transmission results over standard mode fiber using a combination of negative chirp, low extinction ratio, and self-phase modulation transmission techniques in combination are described. The use of pre-transmission signal distortion in combinations with one or more of the other transmission techniques is also described. Pre-transmission signal distortion may be introduced by controlling a modulator with a large symmetric AC signal which causes the modulator to operation in a non-linear region or, alternatively, by using a relatively small non-symmetric AC signal to drive the modulator. Use of the small non-symmetric signal has the advantage of reduced power requirements. The pre-transmission distortion acts to counter some of the distortion introduced by the transmission of the signal over an optic fiber.
