Definitions
- the two comparison signals can be generated in different ways in the invention. Basically, two physically different paths or a common path for the two signals can be assumed.
- the simplest solution, but relatively complex in terms of the components used, is the use of two separate phase comparators, the phase delay element being integrated in the feed line to one of the two phase comparators (generation of the temporal phase shift in the data signal or decoupling signal path).
- the use of a common phase comparator, which is used to generate both comparison signals, is more elegant and cost-effective. When the two comparison signals pass through the phase comparator bidirectionally, this also corresponds to dividing the data signal into two (physical) paths and delaying one path (optical paths of different lengths).
- the decoupling signal can advantageously be obtained from the data signal via an optical coupler, in particular a 3 dB coupler, according to an embodiment of the invention.
- an optical coupler in particular a 3 dB coupler
- the use of the 3dB coupler ensures an even distribution of the signal power over both signal paths.
- the reduction in power per signal path can be compensated for by appropriate amplification components in the phase locked loop. This means that other power distributions can also be made between the two comparison signals, but only to the extent that compensation is still possible and sensible.
- FIG. 1 schematically shows an optoelectric phase locked loop PLL with which the clock signal TS of a data signal DS clocked in high-speed multiplexing (OTDM) on the reception side of a digital optical transmission system can be stably recovered with zero feedback (RZ) of the individual data pulses.
- Optical signal paths are drawn out, electrical ones are shown with dashed lines.
- a decoupling signal CS is first generated from the received data signal DS via an optical decoupler OC. This is then passed through a phase delay element DELAY and its phase is thus shifted in time with respect to the data signal DS.
- phase comparator PC operating with two phase-shifted signals.
- the mode of operation is explained using the diagram in FIG. 8 as an example for a simple (left) and a differential scheme according to the invention (right) known from the prior art.
- switching windows are shown, which were recorded with the photodetectors PD of the electronics of the clock recovery.
- the processed signal is shown, which is used to regulate the voltage-controlled oscillator VCO.
- the switching windows are measured in that the phase comparator PC (here electro-absorbing modulator EAM) is driven electrically at a frequency that is slightly shifted from the frequency of the optical data signal DS.
