Title: Semiconductor optical function element
Inventor: UKO KATSUYUKI
IPC: H01L31/14
Filed: 1991-08-15
Abstract: PURPOSE:To allow the control of light output with a light signal without impairing the high speed characteristic of light by controlling the bias voltage of a resonance tunnel diode(RTD) according to the carriers formed in a light absorption layer by photoirradiation. CONSTITUTION:The control light Pc is absorbed by the absorption layer 4 when the control light Pc is made incident from the upper part and its incident intensity is increased. The number of the electrons passing the RTD 9 receives modulation according to the carriers formed at this time and the past electrons are injected into an active layer 2. The loss of the active layer 2 is decreased and the transmittance of the incident signal light Pi on a low-loss waveguide layer 10 increases. The output light Po emitted from the other end of the waveguide 10' increases as well. On the other hand, the electron transmittance of the RTD 9 decreases and the output light Po decreases as well if the Pc is larger than the control light Pl having adequate intensity. Fabry-Perot resonators are provided at the end faces of the waveguides 10, 10' and the laser threshold value is set, by which the laser beam Po modulated by the control light Pc is obtd. even if there is no input light Pi to the waveguides.

Abstract: PURPOSE:To reduce the effect of an error without increasing additional information such as error correction by including a specific SYNC pattern to a code word or a final part of linked code words and detecting the SYNC pattern when code synchronization is unlocked at reproduction. CONSTITUTION:A signal inputted from an input section 4 in a coder is inputted to a pattern selector 7. The pattern selector 7 selects an information pattern inputted from an information pattern input section 5 and an end pattern inputted from an end pattern input section 6 according to an input signal and links them and outputs the result to an output section 8. A variable length decoding section 15 in a reproduction device stops decoding when an error information input section 13 detects an error and inputted to the section 15 and restarts a variable length decoding according to a head position of a code word inputted from a SYNC pattern detection section 14. Thus, even when an error takes place at the reproduction, the code synchronization of the variable length code is simply restored.
