A photon source capable of emitting, for example, a single photon or a single pair of photons on demand. The photon source may include an excitation region where a single instance of a quantum system is excited using excitation energy. A Stimulated Raman Adiabatic Passage (STIRAP) technique can be used for exciting the quantum system to a desired energy level. The photon source may include a photon emission region physically displaced from the excitation region. A transport device can be used for controllably moving an excited quantum system from the excitation region to the photon emission region. The photon emission region may include a resonant cavity tuned to the de-excitation frequency of the quantum system for inducing de-excitation of the quantum system and emission of a photon. The photon emission resonant cavity may be switchably coupled to an output port by a tunable resonant cavity coupling device.

Single photon source

A high data rate optical signal is inverse multiplexed into a multitude of lower-rate tributaries, each of which is coded by its unique OCDM code, and the combined coded tributaries are injected into a common phase scrambler. Coherent summation of these optically encoded tributaries pass through a shared phase or phase and frequency scrambler before exiting the secure location. The setting of the scrambler acts as the key. The authorized recipient with the correct key retrieves the ones and zeros of the several decoded signals.

OCDM-based all optical multi-level security

An optical communications network incorporating photonic layer security, with secure key exchange without loss of data, and a method of operating the network are disclosed. The network comprises a transmit side and a receive side. The transmit side includes first and second scramblers and a transmit side switch; and the receive side includes first and second descramblers and a receive side switch. The scramblers use encryption keys to encrypt optical signals, and the descramblers use the encryption keys to decrypt the encrypted optical signals. The encryption keys can be updated randomly and at will by installing new encryption keys on the scramblers and descramblers, and the transmit side and receive side switches are synchronized so that all of the optical signals that are encrypted using a new or updated encryption key are decrypted using the same new or updated encryption key.

Secure key distribution for optical code division multiplexed based optical encryption

In an OCDM-based photonic encryption system by applying random noise on unused channels and varying the inter-code phases on realistic framing repetition, an OCDM-based encryption system with provable security guarantees results.

OCDM-based photonic encryption system with provable security

A system and method for transporting encrypted data having a transmitter and a receiver is provided. The transmitter generates a sequence of optical pulses, which are copied and output as identical channels. The identical channels are modulated by a plurality of modulators using data to generate a modulated data signal. Respective spectral phase encoders coupled to each of the plurality of data modulators encode respective modulated data signals using a plurality of mutually orthogonal phase codes that are individually associated with the respective spectral phase encoder. These encoded data signals are combined and code-scrambling by a spectral phase scrambler using a scramble code as an encryption key to generate an encrypted signal. A receiver reverses the encryption to extract the data.

The present invention relates to advances in the field of reconfigurable optical networks. In particular, the present invention provides improvements in the technology of light sources for use in optical networks. The optical network according to the present invention includes a single light source that can be used to emit all of the bands and channels needed for transmission. In particular, the single light source in the optical network of the present invention is a mode-locked laser.

Mode-locked optical amplifier as a source for a wdm-WDM hierarchy architecture

Apparatus and system for transmitting and receiving optical code division multiple access data over an optical network. The apparatus comprises a spectral phase decoder for decoding the encoded optical signal to produce a decoded signal, a time gate for temporally extracting a user signal from the decoded signal, and a demodulator that is operable to extract user data from the user signal. The system preferably comprises a source for generating a sequence of optical pulses, each optical pulse comprising a plurality of spectral lines uniformly spaced in frequency so as to define a frequency bin, a data modulator associated with a subscriber and operable to modulate the sequence of pulses using subscriber data to produce a modulated data signals and a Hadamard encoder associated with the data modulator and operable to spectrally encode the modulated data signal to produce an encoded data signal.

Phase chip frequency-bins optical code division multiple access

A system and method for securing DWDM networks that includes adding background (e.g., white) noise to a level up to the larger of the cross-talk signal or the background channel noise (e.g., amplified spontaneous emission level). The system comprises a white noise generator appropriately placed so that any leaked signals are masked by the white noise generated. Accordingly, only signals intended to be dropped are recoverable because all other signals would not be recoverable from the background white noise.
