Abstract

We propose a simple and all-optical method for fast random number generation based on the laser mode hopping. Through periodically restarting a two-mode laser operating in the bistable state, a random number stream can be generated due to the spontaneous emission noise. To validate the feasibility of this method, we perform a theoretical simulation using the common vertical-cavity surface-emitting laser (VCSEL) with two polarization modes. Numerical results demonstrate that fast 2.5 Gb/s random number streams can be continuously obtained with verified randomness. This scheme provide a fully monolithic solution for random number generator, due to its simple and all-optical structure.

Fast random number generation with spontaneous emission noise of a single-mode semiconductor laser

Jianzhong Zhang, Mingjiang Zhang, Yi Liu +4 more

Abstract We experimentally demonstrate a 12.5 Gb s −1 random number generator based on measuring the spontaneous emission noise of a single-mode semiconductor laser. The spontaneous emission of light is quantum mechanical in nature and is an inborn physical entropy source of true randomness. By combining a high-speed analog-to-digital converter and off-line processing, random numbers are extracted from the spontaneous emission with the verified randomness. The generator is simple, robust, and with no need of accurately tuning the comparison threshold. The use of semiconductor lasers makes it particularly compatible with the delivery of random numbers in optical networks.

Fast and compact VCSEL-based quantum random number generator

Roman Shakhovoy, Е. Ю. Максимова, Violetta Sharoglazova +2 more

Abstract Random number generators (RNGs) are an essential ingredient of modern cryptographic systems. Particular attention is paid today to a special class of RNGs – quantum RNGs, which are attracting close attention of researchers due to the explosive development of quantum key distribution systems, where the use of quantum randomness is a necessary security requirement. A large number of various quantum entropy sources have been proposed over the last 10-15 years. Most of them are based on the use of different quantum optics phenomena, particularly, on the effects occurring in semiconductor lasers. This choice is due to the relatively low cost and ease of use of such devices and the high random bit generation rate available with optical QRNGs. Motivated by these reasons, we study in the present research the QRNG based on variations of light polarization in a vertical-cavity surface-emitting laser (VCSEL). The scheme we propose allows creating an extremely compact and fast optical QRNG, consisting essentially of only a laser and a polarizing beam splitter. We revealed that it is possible to ensure the pulsed operation of a VCSEL in a bistable regime, which is characterized by random switch of light polarization. We show, however, that probabilistic properties of such laser pulses significantly depend on the internal laser parameters as well as on its operating mode. Understanding these properties is fundamentally important for the correct assessment of the quantum noise contribution and, consequently, for the subsequent post-processing of digitized random sequences.

Random number generation based on polarization mode noise of vertical-cavity surface-emitting lasers

M-Y Zhu, Yijia Liu, Q. F. Yu +1 more

We propose an implementation of random number generation based on the measurement of polarization mode noise in vertical-cavity surface-emitting lasers (VCSEL). By measuring the phase difference between two laser beams with perpendicular polarization directions, a 40 Gbps generation speed is achieved with a simple post-processing method. The random sequence we generated passes both the standard statistical test suites (Diehard and NIST-STS) and 3σ criterion. Our setup is compact and easy for implementation, and it also has a better efficiency in extracting randomness from VCSEL compared with existing methods.

Generació de números aleatoris quàntics basats en la dinàmica de polarització en VCSELs

Mir Pou, Blanca

Random numbers are essential in a great variety of applications ranging from stochastic simulations to secure communications. In this thesis, we report a technique for quantum random number generation based on the dynamics of light polarization in a vertical-cavity surface-emitting laser (VCSEL). We show that two linearly polarized modes with slightly different wavelengths and gains appear within the cavity of the VCSEL laser. Due to spontaneous emission noise, VCSELs undergo random polarization switching at certain bias currents. We experimentally analyze the probability of appearance of each mode as a function of the biasing conditions. By periodically modulating a VCSEL at the polarization switching region defined under continuous-wave operation, random digits can be generated directly from the output of the pulsed VCSEL at a much higher bit rate. The results presented in this research demonstrate the feasibility of generating random numbers at rates up to 100 Mbit/s using a commercial VCSEL.

Truly random number generation based on measurement of phase noise of a laser

Hong Mei Guo, Wenzhuo Tang, Yu Liu +1 more

We present a simple approach to realize truly random number generator based on measuring the phase noise of a single-mode vertical cavity surface emitting laser. The true randomness of the quantum phase noise originates from the spontaneous emission of photons and the random bit generation rate is ultimately limited only by the laser linewidth. With the final bit generation rate of 20 Mbit/s, the truly random bit sequence guaranteed by the uncertainty principle of quantum mechanics passes the three standard randomness tests (ENT, Diehard, and NIST Statistical Test Suites). Moreover, a continuously generated random bit sequence, with length up to 14 Gbit, is verified by two additional criteria for its true randomness.

Random bits from quantum jumps

An effective and robust method for generating random bits from random time intervals between quantum jumps of optical field is proposed and experimentally tested with spontaneous switchings in a bistable vertical-cavity surface-emitting laser. This algorithm allows one to avoid the problem of biasing in the output bit stream as well as to obtain low correlation between generated bits. A comprehensive comparative statistical analysis of different methods of extraction of random bits from experimentally measured time intervals between spontaneous polarization switchings in a bistable vertical-cavity surface-emitting laser shows the advantage of the proposed method.
