In the field of optical communications, electro-absorption (EA) modulators (12) can be used to modulate electromagnetic radiation (50) to generate a modulated signal (52). A change in temperature of the EA modulator (12) during operation can change the extinction ratio and average power of the modulated signal (52). In order to maintain the extinction ratio and average power of the modulated signal (52) it is known to monitor the temperature of the EA modulator (12) and generate a feedback signal to cool or heat the EA modulator (12) as appropriate. Consequently, the present invention provides a control loop apparatus (10) for maintaining a constant extinction ratio and an average power of the modulated signal (52) without the need for the monitoring of the temperature of the EA modulator (12) and without the need to heat or cool the EA modulator (12). |

| A tunable liquid crystal switch (10) is disclosed. An electronic controller (30) provides an electronic drive scheme for achieving low intra-channel crosstalk of less than -40dB using only electronic compensation. A cross-talk less than -50dB is provided by combining coarse temperature tuning and electronic compensation. This is achieved by designing the thickness (d) of the liquid crystal device (20) to cause a minimum to occur at a wavelength longer than a longest operating wavelength and at a temperature greater than a maximum operating temperature. This ensures that the liquid crystal device (20) is tunable over all operating wavelengths and temperatures using electronic compensation. | ||||||

| 147 | Athermalized birefringent filter apparatus and method | EP08160140.3 | 2008-07-10 | EP2015133B1 | 2018-11-21 | Miller, Peter; Mirkin, Leo |
| An athermalized birefringent filter (102) for shifts in center wavelength and in bandwidth incorporates fixed retarder elements such as quartz or film retarders, along with electrically-variable retarder elements such as liquid crystal variable retarder cells. A control mechanism determines the amount of thermal drift in the fixed retarder element and produces an equal change in the variable retarder element. The sign of the change depends on whether the variable retarder element adds its retardance with that of the fixed retarder element, or opposes it. This change compensates for the thermal drift of the fixed retarder element. Further, the variable retarder element is constructed to provide the necessary range of retardance adjustment for spectral tuning and thermal compensation over a target thermal range. The control mechanism ensures that, for any specified wavelength, the birefringent filter operates in the same order over the full target thermal range. Multispectral imaging systems (100) are provided based on these filters which provide athermalized response. | ||||||
| 148 | ARRAY SUBSTRATE, LIQUID CRYSTAL DISPLAY PANEL AND DISPLAY DEVICE | EP15766377 | 2015-04-28 | EP3200012A4 | 2018-05-16 | WU HAO |
| The embodiments of the present invention disclose an array substrate, a liquid crystal display panel and a display device. Low temperature compensation circuits one-to-one corresponding to the data lines are added to the peripheral area of the array substrate; each low temperature compensation circuit comprises a first branch and a second branch connected in parallel; wherein the first branch comprises a divider resistance; the second branch comprises a diode and a capacitance connected in series; in the second branch the position of the diode and the position of the capacitance can be interchanged. Since the voltage difference between the both terminals of the diode rises with the temperature decreasing, the voltage difference on the route comprising the diode and the capacitance rises when the temperature decreases; a divider resistance is used in the route to divide the voltage of the voltage signal inputted at the data signal receiving terminal, reducing the voltage signal inputted to the input terminal of the data line. The reduced voltage signal brings a higher transmittance, compensating the integral shift of the voltage-transmittance curve in low temperature environment, such that the voltage-transmittance curve at low temperature is kept in accordance with that at normal temperature. | ||||||

The system includes at least one optically transmissive element (TOC) that is held by a differential pressure in thermal contact with a heat sink assembly. In one embodiment, the heat sink assembly includes an optically transparent heat conductor (THC) attached to at least one face of the TOC. A vacuum formed between adjacent faces of the TOC and THC urges the facing planar surfaces into thermal contact with one another. Waste heat generated in the TOC is conducted to the THC. The temperature gradient inside the TOC is maintained substantially parallel to the direction of a laser beam being directed through the THC so that a given phase front of the beam exposes TOC material to the same temperature. As a result, the TOC does not perturb the phase front of the laser beam. | ||||||
