Title: Method of variably attenuating a beam of projection light in an optical system of a microlithographic apparatus
Inventor: VLADIMIR DAVYDENKO
IPC: G03F7/20
Filed: 2016-05-12
Abstract: A pattern of light absorbing regions is created on or within a diffractive or reflective optical element 44 mounted in the optical system of a microlithographic apparatus. Projec­tion light is directed onto the absorption pattern then either the light absorbing regions (Fig. 6: 120) disappear by themselves or they are actively removed. These steps are carried out at least at two consecutive portions (Fig. 4: 56a, 56b) of the optical element, so that at a given time the projection light is directed either to the first or to the second portion. As an example a rotatable disk shaped optical element 44 may be placed at one of the pupil planes 36, 38 of the projection objective 20 as a time variable apodization filter. A print head 50 may be used to form absorbing regions 58 which are removed using an erasing head 52, or a laser printer may provide writing light (Fig. 4: 72) causing illuminated areas on a rotating photosensitive drum (Fig. 4: 78) to attract toner from a toner drum (Fig. 4: 80). Writing light from a laser printer may be directed onto regions of photochromic materials including CaF2 or BaF2 doped with rare earth elements, to cause excited state absorption (ESA). Light absorbing regions may disappear as a result of recombination processes, or using an erasing light, and a rotating filter plate (Fig. 10: 344) including regions of the material may be placed very close to the mask plane. Excited state absorption may alternatively be induced in a replaceable polymer film (Fig. 12a: 445) formed on a substrate.

Title: Fully supported c-ring slip retention system
Inventor: Steven Zakharia
IPC: E21B43/10
Filed: 2017-02-06
Abstract: A c-ring slip retention system and method for extraction of the c-ring slip is provided. The c-ring slip retention system 14 uses an axially movable support sleeve 26 with a support ring 28 for securing the c-ring slip 16 against a retention lip 24 of the liner hanger body 12. The c-ring slip may comprise a keyed profile 50 to complement an inner wall profile 54 on the retention lip. The retention system prevents the c-ring slip from being prematurely extracted from a liner hanger body while the liner hanger is lowered through a borehole. The c-ring slip retention system may also include anti rotation features that prevent the c-ring slip from rotating relative to the liner hanger body. A single actuation of the support sleeve in an axial direction unlocks the c-ring slip from the retention lip, may disengage any anti-rotation features, compress the c-ring slip out of the keyed profile, and extract the c-ring slip from the liner hanger body.

Title: A quantum communication system
Inventor: JAMES DYNES
IPC: H04B10/70
Filed: 2014-06-23
Abstract: This application concerns a quantum communication system comprising a transmitter 1 which is connected to a receiver 17 by an optical fibre 16. The transmitter and the receiver each include an interferometer, each comprising first and second paths. One path of one of the interferometers includes an attenuator 70 and one path of each of the interferometers includes a phase modulator 6, 26. The transmitter paths are combined in a polarizing beam splitter 9, which rotates the polarization of one of its input paths by 90 degrees, so that pulses with orthogonal polarizations are transmitted over the fibre. These pulses suffer an intensity mismatch due to polarization dependent loss (PDL). Upon entering the receiver 17, the intensity mismatch is shown by the different heights of pulses 71 and 41. By adjusting the attenuator 70 this intensity mismatch imparted on the light pulses as they travel down the optical link can be cancelled out. Thus the pulse heights in the receiver interferometer paths can be equalized. The attenuator is controlled to achieve this, preferably electronically and in real-time.
