摘要： A method relating to the calibration of tuneable lasers is described. The method provides for the provision of correct control currents so as to achieve each of desired output frequencies from the laser. The correct currents are determined by forming a matrix of the output characteristics of the laser at specific tuning currents and processing that matrix to determine stable operating points within the matrix.

摘要： The invention provides a method and system for compensating variations in tuning efficiency and power of a multi-section tunable laser diode. The invention comprises a means to obtain a set of values for a specific section of the laser diode and a means to normalise the values to compensate the non-linearities in the set of values, hence compensating for variations in the tuning efficiency for that particular section of the laser diode. The invention is advantageous in that it is generic and can be applied to several different types of lasers. A further advantage of the invention is that the mode width can be determined as well as the mode modulation of the tunable laser.

摘要： A boat docking system having a V-shaped horizontal floating structure held together by two underwater bents. The structure is constructed of two flexible fiberglass rods which allows the structure to open up and conform to a shape of a boat inserted into the V-shape. The two bents acts as spring clips to open up the V-shape against resilient force, and to thereafter close around the contour of the boat. The V-shape structure is floated intermittently by tubular foam buoys fixed along lengths of the V-shape structure. A strut anchored to the dock at one end and attached to the V-shape structure at another end with a sliding joint gives stability to the floating structure as well as provides the proper distance during docking of the boat to the walkway.
