    摘要： An optical device includes a first multi-mode waveguide, a first optical coupler coupled to the first multi-mode waveguide, the first coupler being tapered and curved, and a first single-mode waveguide having a first end coupled to the first optical coupler. The optical device maybe used in an optical delay device. A method of propagating light in a first multi-mode waveguide toward a first optical coupler, propagating the light in the first optical coupler toward a first single-mode waveguide, the first optical coupler being tapered and curved, and propagating the light along the first single-mode waveguide is also disclosed.

    摘要： A method of making an erythroid cell comprising elevated levels of a target protein or polypeptide, the method comprising: a) provision of an erythroid progenitor which is able to express the target protein or polypeptide; b) expression of the target protein or polypeptide; and c) maturation of the erythroid progenitor into the erythroid cell; wherein during maturation of the erythroid progenitor into the erythroid cell, the target protein or polypeptide is configured and/or inhibited such that ubiquitination of the target protein or polypeptide is hindered or prevented. Erythroid cells, pharmaceutical compositions and methods of use related thereto, and a method of screening for proteins or polypeptides degraded by ubiquitination during maturation of an erythroid progenitor are also provided.

    摘要： There is provided an integrated-optic transmitter for transmitting light pulses to a further optical apparatus for generating a quantum cryptographic key according to at least one quantum cryptography technique. There is also provided an integrated-optic receiver for generating a quantum cryptographic key from light pulses received from a further optical apparatus. The transmitter apparatus splits incoming light into two paths to temporally separate the split light pulses and controls the output intensity of each split pulse as well as the phase of at least one of the split pulses. The receiver apparatus receives first and second light pulses and controls the output intensity of each said pulse between a first and a second optical detector. The light input into the second detector passes through an integrated element that controls the amount of light output into two paths that recombine before at least a portion is output to the second detector.
