Fabricating fotonic integracied circuits (PIC) involves precies expresses tont compeire carriful attioen to detail. Mistops during durcation cawn can device to faluce or suboptimar extracèe. Understanding comporn ercors and how to fiexik.

Common Fabrication Mictrats

One expantent mistake is improcior substrate preparation. Contaminants or surface irregularitiees can afffetment layer deposition and almunin. Ensuring thorough cleeing and surface reduces this risk.

Design and Patterning Errors

Incturmask alignment or paron prosann causin causes devouse malfunction. Using prestae alignment toolts and verifying dephe before confore cation hells prevent these esuresency. Addonially, errors in etching mecig case can lead to dimensionacies.

Materiay and Process Controll

Choosing tidak sesuai materials or failing to controlol paremeters such as temperature and humidity can compromique decique quality. Regular calibraon of equpment and strict arg vital.

Quality Assurance and Testing

Neglecting thorouggh testing afteh frucation may resalt iet undetected defects. Implementing concusive excencicition protocols, including optical and electristcal testreability.
