Abstract:
1. An optoelectronic apparatus comprising: an optical emitter; an emitter driver circuit coupled to drive the optical emitter; a controller circuit coupled to the emitter driver circuit, the controller circuit configured to provide control signals to the emitter driver circuit to maintain consistent optical performance of the optical emitter over a predefined range of temperatures and to deviate from consistent optical performance utilizing a specified deviation methodology for temperatures outside the predefined range of temperatures; and a memory coupled to the controller circuit and having stored therein temperature values and at least two control values for the emitter driver circuit for at least some temperature values, and the memory further having stored therein a value for controlling an optical emitter bias current and a value for controlling a current swing of the optical emitter in association with at least one of the temperature values; wherein the controller circuit generates the control signals based at least in part on two of the control values that are associated with the same temperature value in the memory.
