[@virajsinghbhutoria]

Sir need a video on rise time and r s time maths of LED.

[@pavanyerukula3157]

You might have explained about Braggs reflector and Braggs wavelength

[@hammadmohamed5970]

Pls make a video on quantum well laser

[@PriyankaKumari-xf4bt]

Sir please explain about electrical and optical confinement of laser diode

[@DUMPAKASIVISHWANADHAM]

Semiconduction injection laser diode (ILD): Structure of GaAS homo-junction Injection laser diode with Fabry-Perot cavity: Structure of Double heterojunction injection laser diode: Hetero junction laser divided into two types 1. Edge emitting laser injection(gives laser output through mirror and) 2. Surface emitting injection laser (gives laser output through surface of the diode) Edge emitting injection lasers are divided in to two types 1. Gain guided lasers 2. Index guide laser Sir please make a video explain all these laser, apart from fabry perot as you have already explained it.

[@sakshisharma2930]

Sir, please explain Distributed Bragg reflector and Vertical Cavity surface laser also

[@ramakrishnapothula7276]

Super sir, Can you explain OMI(optical modulation Index

[@EngineeringFunda]

I have noted it now

[@kaushalpanchalk.p4930]

What is definition of brag wavelength

[@pravasthi-mc4xj]

Superluminiscent led expalin plz

[@crispinvincent9702]

Sir please take quantum efficiency of laser and resonant frequency,

[@aishwaryarajawat6938]

Sir gain and index guided laser pr bi video mno plz

[@rishabhsharma2969]

Sir please explain vcsel laser too

[@amaragrawal110]

It's my request can you upload your videos in hindi

[@EngineeringFunda]

I am not good in Hindi, I mean we gujarati people speaks deshi hindi.

[@tathagatkatolkar1389]

Dbr and dfb laser working

[@nagendrababul]

🙏🙏🙏🙏

[@abayjeetrana6932]

Is topic k notes dedo sir

[@EngineeringFunda]

Go through my android application engineering funda

[@akshatgupta3005]

Sir you are just reading notes nothing else , this is not teaching . Please don't just read .

[@abhijitmagar8877]

too much boring cause you always talk in english please refer hindi instead of english
