Abstract

According to one embodiment of the present invention, a wavelength-shifted dynamic intelligent bidirectional access optical system utilizes key optical elements such as: a quantum dot enabled semiconductor optical amplifier, a phase modulator and an intensity modulator to provide upstream optical signals. These key optical elements reduce the Rayleigh backscattering effect on the transmission of optical signals. Reduced Rayleigh backscattering effect enables a longer-reach access network topology (more than any other current access network topology) between a subscriber unit and a super node (e.g., many local nodes collapsed into one super node). Such a longer-reach access network topology eliminates operational costs and capital costs related to a vast array of middle equipment such as routers and switches, which would otherwise be needed between super nodes and many remote nodes. Furthermore, a wavelength to a subscriber unit may be protected and dynamically varied for on-Demand bandwidth, information and services and also a subscriber's unit may be configured with any array of connectivity options. Integrated micro-processors, wireless devices, wireless sensors, RFID sensors, and batteries incorporated into an intelligent device may be used to sense the environment, to process information, to initiate action and to communicate with other similar devices. Data interpretation, pattern recognition and reasoning technologies may be utilized to allow these devices to communicate with and/or without human intervention and to operate independently and intelligently. Such independent interactions with other similar devices (integrated with micro-processors, wireless devices, wireless sensors, RFID sensors and batteries) can enable the Internet of Things and/or machine-to-machine communication via an embedded algorithm/software. Such an intelligent device can also act as the remote-control for life and health.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • FIG. 1 shows an access optical network 100, which is a wavelength-shifted dynamic bidirectional system, includes a super node 101, many local nodes 102 and many remote nodes 103.
  • An optical network 100 connects to many local nodes 102, many remote nodes 103 and a large number of subscriber units 340. At a super node 101, a number of fast switching wavelength stabilized tunable lasers 120 provide specific downstream optical signals of selected distinct wavelengths, each selected distinct wavelength being modulated by the corresponding modulators 140. The modulated wavelengths are then combined by wavelength combiner 160 and amplified by an erbium-doped fiber amplifier (EDFA) 220. The amplified wavelengths pass through a circulator 260 to be transmitted on a dispersion-compensated, single-mode optical fiber 280 to a remote node 103.
  • The modulated wavelengths (optical signals) are transmitted over a dispersion-compensated single-mode optical fiber 280 and then are decombined by a wavelength combiner/decombiner 300 in a remote node 103 and filtered by a tunable optical bandpass filter 240 in order to recover the selected distinct wavelengths (optical signals). The filtered wavelengths are then further decombined by an optical power combiner/decombiner 320 and are sent to multiple subscriber units 340.
  • Also at a local node 102 includes fast switching wavelength stabilized tunable lasers 120, which provide optical signals of selected distinct wavelengths that are each offset from the corresponding set of selected distinct wavelengths generated at a super node 101. These selected distinct offset wavelengths at local node 102 are modulated by modulators 140 and amplified by an erbium-doped fiber amplifier (EDFA) 220.
  • The selected amplified distinct wavelengths (optical signals) transmit through an optical power combiner/decombiner 320 and are sent to multiple subscriber units 340 for upstream optical signals.
  • The upstream optical signals are returned through an optical power combiner/decombiner 320, a tunable optical bandpass filter 240, and a wavelength combiner/decombiner 300. The upstream optical signals are transmitted over a dispersion-compensated single-mode optical fiber 280 to a circulator 260 of a super node 101.
  • A circulator 260 provides the wavelengths to a tunable optical bandpass filter 240, an erbium-doped fiber amplifier (EDFA) 220 and a wavelength decombiner 180 for detection by a larger number of avalanche photodiodes 200 for each distinctly selected wavelength (optical signal).
  • FIG. 2 shows an optical network 100 where a wavelength to a subscriber unit 340 can be dynamically varied utilizing M:M cyclic arrayed waveguide grating router(s) 250. Also a wavelength to and from a subscriber unit 340 can be protected by a 2×2 optical switch (not shown in the FIG. 2). Downstream and upstream optical signals can be separated via a ring network topology of single-mode optical fibers 280, according to one embodiment of the present invention.
  • All possible switched output wavelengths of the fast switching wavelength stabilized tunable lasers 120 are arranged or displayed at the M outputs of the M:M cyclic arrayed waveguide grating router 250 because of the free spectral range periodic property of the M:M cyclic arrayed waveguide grating router 250. The M:M cyclic arrayed waveguide grating router 250 offers the flexibility of routing more than one wavelength to any subscriber unit 340 for on-demand bandwidth, information and services.
  • FIG. 3A shows an exemplary configuration of a subscriber unit 340, according to one embodiment of the present invention. As shown in FIGS. 3A, 4 and 5, a subscriber unit includes a tunable optical bandpass filter 240, an avalanche photodiode 200, a circulator 260, optical processing components 360-420, an electrical to optical amplifier circuit 440, an avalanche photodiode circuit 460 and a media access and algorithm flow/quality of service (QoS) management controller 480.
