Method for attaching multiple light sources to an optoelectronic module

A method of coupling a plurality of n light sources to an optoelectronic module comprising a plurality of n optical input ports and an optical output port, comprising the steps of:

• (a) attaching the optoelectronic module to a carrier member;
• (b) coupling a light detector to the optical output port;
• (c) sequentially moving each of the plurality of n light sources adjacent a separate one of the plurality of n optical input ports while pulsing the light source being moved with a low power signal sufficient to prevent failure of the light source;
• (d) attaching each of the light sources adjacent the separate one of the n optical input ports when a maximum light intensity signal propagating through the optoelectronic module from the light source is detected by the light detector;
• and
• (e) attaching, if needed, a heat dissipating means to a base of the carrier member capable of removing sufficient heat from the n light sources and the optoelectronic module to prevent overheating thereof during normal operation thereof.

A method of forming an assembly comprising n radiation sources which each require heat dissipating means during normal operation, where n is a number greater than one, and a radiation sensitive detector having m inputs, where m is a number greater than one, and having an output port, the method comprising the steps of:

• (a) attaching the radiation detector to a carrier member;
• (b) turning on a first one of the n radiation sources and operating same at a substantially lower power than is used during normal operation such that same does not overheat even without the heat dissipating means being coupled thereto;
• (c) positioning the first radiation source of step (b) relative to a first one of the m inputs of the detector such that radiation emitted by the first radiation source is incident on the first input of the detector;
• (d) repositioning the first radiation source while it is powered with the substantially lower power than is used during normal operation until a signal emitted at the output of the detector reaches a maximum level;
• (e) fixedly attaching the first radiation source to the carrier member;
• (f) repeating the steps (b), (c), (d), and (e) for a second one of the n radiation sources;
• (g) repeating the steps (b), (c), (d), and (e) for any additional radiation sources;
• and
• (h) attaching, if needed, a heat dissipating means to a base of the carrier member capable of removing sufficient heat from the n radiation sources and the radiation detector to prevent overheating thereof during normal operation thereof.

A method of forming an assembly comprising n chips, where n is greater than 1, with at least one of the n chips having formed therein two radiation sources which requires heat dissipating means during normal operation thereof, with each of the remaining n−1 chips having formed therein at least one radiation source which requires heat dissipating means during normal operation thereof, and a radiation detector comprising a plurality of radiation input ports and an output port, the method comprising the steps of:

• (a) attaching the radiation detector on a carrier member;
