Abstract: This application discloses a temperature feedback control apparatus, method. The method includes two electric switches, a feedback control unit and an optical component. A first electric switch is configured to control that only a first channel of at least two channels that correspond to the first electric switch is conducted at a moment, to feed back an optical signal of a target optical component connected to the first channel to the feedback control unit. The feedback control unit is configured to calculate temperature of the corresponding optical component based on an electrical signal converted from the optical signal, to obtain a control signal. The second electric switch is configured to control, when the first channel is conducted, that only the second channel is conducted, to transmit the control signal to the target optical component to adjust its temperature. The optical component connects to both the first and second channels.

Abstract: A light emitting structure has quantum wells grown on a coalesced substrate stemming from nanocolumns. The crystal structure is very low in defects and efficiency of light production is good. By growing the nanocolumns at a lower temperature, the quantum well structure is better matched to the coalesced substrate and efficiency is improved.

Abstract: The array of gallium-nitride (GaN) nanocolumns have quantum wells in a polar c-plane or in a semi-polar plane to emit light directed to ends of the nanocolumns and an interstitial filler material with light emitted in the nanocolumns being guided to exit from an end of the nanocolumns.

Abstract: An apparatus for optical processing of a signal includes an optical sampler, an optical neural network and a phase shift controller. The optical sampler obtains parallel optical samples by sampling a continuous optical signal. The optical neural network optically processes the parallel optical samples and provides a final output optical signal resulting from the processing. The optical neural network includes interconnected optical neurons. Each of the optical neurons inputs multiple optical signals and outputs an optical signal which is a weighted sum of the input optical signals. The weightings are established by phase-shifting the input optical signals prior to the summation. The phase shift controller controls the phase-shifting so as to obtain required weightings for the input optical signals.

Abstract: Disclosed are systems and methods for providing transport layer encryption with an intermediate electronic message managing service interposed in a message path of an electronic message to be sent from a sending server to an intended receiving server across a computer network. To implement TLS in such a managed e-mail services context, given that a managed e-mail service is inserted into the message delivery path, the transport layer security protocols are simultaneously established along both the link from the sending server to the managed e-mail service and from the receiving server to the managed e-mail service, with the managed e-mail service providing a “proxy” connection for communication between the sending server and the receiving server.

Abstract: Partial speed and full speed programming are achieved for a non-volatile memory system. During a program operation, in a first time period, bit lines of storage elements to be inhibited are pre-charged, while bit line of storage elements to be programmed at a partial speed and bit lines of storage elements to be programmed at a full speed are fixed. In a second time period, the bit lines of storage elements to be programmed at the partial speed are driven higher, while the bit lines of storage elements to be inhibited are floated and the bit line of storage elements to be programmed remain fixed. In a third time period, the bit lines of storage elements to be inhibited are driven higher while the bit lines of the storage elements to be programmed at the partial speed or the full speed are floated so that they couple higher.
