An experimental four-channel optical time-division multiplexed transmission system is described and the first demonstration of fiber transmission at a bit rate of 16 Gb/s is reported. In this experiment, data at 16 Gb/s has been transmitted over 8 km of fiber with a bit error rate below 10 sup (-9).

Composite-cavity semiconductor lasers using integral single- mode fiber resonators are capable of producing short-duration mode-locked optical pulses at very high repetition rates. This paper summarizes recent experiments using a composite- cavity structure with an efficient single-mode fiber output port. The dependence of pulse width on the electrical drive waveform and ...

IFS programmer's manual (release 2).

  • Vo K.

The Interpretive Frame System (IFS) is a tool for creating application software with sophisticated interactive interfaces. IFS is based on the notion of a frame network. A frame network consists of many interconnected modules called frames, each of which represents a logical activity in the system. Frames are written in ...

POLARIZATION PRESERVATION IN MULTIMODE FIBERS.

  • Pleibel W.
  • Stolen R.
  • Wagner R.

Birefringent multimode fibres have been found to preserve polarisation except for one mode near cutoff. Experimental observations and theoretical considerations show that polarisation ratios better than 20 dB are possible, offering the potential for building polarisation-sensitive multimode fibre components.

LOW-LOSS SPLICES FOR SINGLE-MODE FIBERS.

  • Derosier R.
  • Tynes A.

A technique for producing low-loss splices in single-mode fibres has been developed and evaluated. The splices are made by sandwiching the fibre butt-joint ends between a glass V-groove block and a flat glass plate, both of which are made by fibre-drawing techniques. A new splice-loss measuring technique is described. The ...

AN ACOUSTIC SURFACE WAVE ANALOG TO DIGITAL CONVERTER.

  • Baldwin G.
  • Coldren L.

An analogue-digital convertor that employs an acoustic-surface-wave transducer code plate is described. An experimental a.d. encoder with 4 bits of resolution and a 3 MHz sampling rate has been implemented with an LiNbO3 surface-wave structure.

NOISE FROM NEUTRON INDUCED DEFECTS IN JUNCTION FIELD EFFECT TRANSISTORS.

  • Kern H.
  • Mc Kenzie J.

Neutron damage centers in the depletion region between the gates and channel of a JFET fluctuate in charge and modulate the drain current. Thus, they create noise. The noise from 1012 14.8 MeV neutrons/cm2 is easily measured. Temperature dependence of leakage current indicates a neutron damage generation-recombination level effective at ...

6000 Megacycle/Sec Radio Relay System for Broad-band, long Haul Service in the Bell System.

  • Mcdavitt M.

DEVELOPMENT of microwave communication facilities for Bell System use was undertaken in 1945, taking advantage of prewar research at Bell Telephone Laboratories and of the impetus in technology achieved during the war years. In 1947, an experimental 4,000-mc/sec (megacycle per second) system of moderate bandwidth (TD-X)1 was established between New ...

Surface Conduction Channels in Germanium - An Interim Report.

  • Christensen H.

Surface conduction channels on both the n-type and the p-type region of a p-n junction of germanium have been produced and investigated. Channels on the n-type region were produced by an oxygen rich surface environment and those on the p-side were produced by high humidity. At an intermediate, 75 per ...

Attenuator Materials, Attenuators and Dimensions for Microwaves- (I).

  • Frosch C.
  • Rigterink M.
  • Teal G.

Microwave development has brought with it many related devices, one class of which is circuit elements having the property of attenuating or absorbing microwaves. Investigation of the microwave properties of a variety of solids led to the application of electrically in-homogeneous ceramic and plastic materials such as silicon carbide dispersed ...

DYNAMICAL BEHAVIOR OF A FLEXIBLE, MATERIALLY DAMPED TOWED CABLE.

  • Cannon T.
  • Genin J.

The three-dimensional equations of motion of a flexible towed cable are developed. A closed-form approximation for the equilibrium shape of a cable subjected to arbitrary aerodynamic loading is developed and used in the study of a heavy, vibrating tow cable. Natural frequencies of vibration and cable shapes are computed for ...

Resource Allocation for Uplink Grant-Free Ultra-Reliable and Low Latency Communications

Ultra-Reliable and Low Latency Communications (URLLC) is an important emerging area for the fifth generation (5G) cellular network. The requirements for URLLC are as stringent as 1e10-5 reliability for a 32-byte packet with user plane latency of 1 ms. To achieve these requirements, grant-free transmission with repetitions of data packet ...
