Photonics Technician roadmap

Stage 1 of 3 · about 12 weeks

Foundations

Understand how light behaves, do the basic math, work safely around lasers, and use core lab instruments with confidence.

1. 1

   Geometric and wave optics basics

   Every task you will do, from aligning a beam to choosing a lens, comes from a few rules: reflection, refraction, focal length, interference and diffraction. If you know why a beam bends, you can fix it when it does not go where it should.

2. 2

   Technical math and unit handling

   Technicians constantly convert units and compute things such as power in dBm, loss in dB, wavelength and frequency. Mistakes here create bad data, and bad data wastes an engineer's week.

3. 3

   Laser safety

   Lasers can permanently damage eyes in a fraction of a second, often from reflections you cannot see. Employers will not let you touch a bench until they trust your safety habits, so this is your entry ticket.

4. 4

   Basic electronics and instruments

   Lasers, detectors and drivers are electronic devices. You will read oscilloscopes, use multimeters and solder, so you need to know voltage, current, resistance and how to measure them without damaging parts.

5. 5

   Clean handling and lab discipline

   A fingerprint on a lens or a speck of dust on a fiber end face can ruin a test or a product. Clean room rules exist because tiny contamination causes expensive failures.

Then 2 more stages (about 56 weeks in all) with lessons, drills, projects, 6 interview questions with strong answers and free resources.
