Method and apparatus for reducing electrical and thermal crosstalk of a laser array

A method for maintaining an operating characteristic of lasers within a laser array comprising:

• determining an operating state of each laser in the laser array;
• selecting compensation values from a table corresponding to the determined operating state of the laser array;
• generating drive signals in accordance with the compensation values;
• and
• providing the drive signals to selective ones of dissipation elements within the laser array.

A method for adjusting operating wavelengths of lasers within a laser array comprising:

• determining the operating wavelengths of the lasers under initial operating conditions;
• computing wavelength errors based on the determined operating wavelengths and specified wavelengths;
• determining temperture-to-wavelength coefficients of the lasers;
• determining thermal coupling coefficients of the dissipation elements to the lasers;
• calculating compensation values that reduce the wavelength errors based on the wavelength errors, the temperature-to-wavelength coefficients, and the thermal coupling coefficients;
• generating drive signals in accordance with the compensation values;
• and
• providing the drive signals to selective ones of dissipation elements within the laser array.
