Disclosed is a Photonic Phase Locked Loop (PPLL) detector/discriminator, which makes possible a system for optically transmitting electromagnetic signals through a transmission medium (such as optical fiber, optical waveguide, underwater, in biological tissue, or in free space) with high sensitivity and extremely high dynamic range exceeding what is possible with present optical intensity modulated (AM) systems. Information is encoded on an optical carrier through the use of phase modulation (PM) or frequency modulation (FM). This information is subsequently demodulated into an accessible form through the use of the PPLL.

A linear phase demodulator/down-converter comprises an optical amplitude modulator for modulating the amplitude of an optical input signal, a photo-detector, a loop filter and an optical phase modulator provided with a light source. The optical phase modulator/down-converter provides optical down conversion, optical up conversion, or a combination thereof. The photo-detector can be a balanced photo-detector. Linear phase demodulation and/or down conversion is performed completely in the optical domain.

Systems and methods are provided to facilitate online transactions via mobile communications. In one aspect, a system includes a data storage facility and an interchange coupled with the data storage facility that stores purchase receipts in association with phone numbers. The interchange includes a common format processor and a plurality of converters to interface with a plurality of different controllers of mobile communications. The converters are configured to communicate with the controllers in different formats and with the common format processor in a common format, to obtain a confirmation of a payment request that identifies a phone number, a merchant and a purchase from the merchant. After a confirmation is received, the interchange is to use funds associated with the phone number to pay the merchant for the purchase and to receive and store a receipt for the purchase from the merchant.

Systems and methods are provided to facilitate repeated purchase and payment transactions. In one aspect, a system includes an interchange and a data storage facility configured to store payment transaction records associated with phone numbers. The interchange includes a common format processor and a plurality of converters to interface with a plurality of different controllers of mobile communications. The converters are configured to communicate with the controllers in different formats and to communicate with the common format processor in a common format. The common format processor is configured to identify a prior payment transaction associated with a phone number in response to a message from a mobile phone having the phone number, communicate with a merchant to repeat a purchase according to the prior payment transaction, and transmit via one of the converters premium messages to the mobile phone to collect funds for a payment to repeat the purchase.

Systems and methods to propagate and redeem offers via mobile communications. In one aspect, a system includes an interchange and a data storage facility storing a value in association with a first phone number. The interchange includes a common format processor and a plurality of converters to interface with a plurality of different controllers of mobile communications. The converters are configured to communicate with the common format processor in a common format and with the controllers in different formats. The common format processor is to re-associate the value with a second phone number and to use one converter of the converters to communicate a reference of the value to a telephonic apparatus at the second phone number, in response to a request from a telephonic apparatus at the first phone number, when the request includes the second phone number and a reference to the value.

Systems and methods are provided to facilitate online transactions via mobile communications. In one aspect, a system includes a data storage facility and an interchange coupled with the data storage facility that stores data associating a phone number with an account, such as a balance of the account, identification information of a plurality of funding sources, and security data for authentication. The interchange includes a common format processor and a plurality of converters to interface with a plurality of different controllers of mobile communications. The converters are configured to communicate with the controllers in different formats and with the common format processor in a common format, to facilitate authentication of the payment requests received from various payment terminals. The requests are authenticated via both the security data and communications with a mobile phone having the phone number. After the authentication, the payments are effected using the account.

Systems and methods are provided to automate transactions via mobile communications. In one aspect, a system includes a data storage facility to store data associating phone numbers with accounts and an interchange coupled with the data storage facility. The interchange includes a common format processor and a plurality of converters to interface with a plurality of different controllers of mobile communications. The converters are configured to communicate with the controllers in different formats and with the common format processor in a common format. The common format processor has an application programming interface to receive requests, such as a charge request having an identification of a phone number, an identification of a merchant, and an amount, and a status request having an identification of the first request, and is to transmit a message to a telephonic apparatus at the phone number to confirm the charge request, using one of the converters.
