Using the photodiode circuit wizard at: http://www.analog.com/designtools/en/photodiode/ it shows that a BPW34 + AD8066 should be able to output a bandwith with 500kHz:
The AD8066 can be found here: https://www.ebay.de/itm/261101423440

KM There is a small notch on the photodiode to help with the orientation, this should be the correct layout:
Edit:
Test with a Nokia 6 at <17% brightness:

Edit2:
I tried to create a pwm signal with the arduino status led:
Code:
void setup()
{
pinMode(13, OUTPUT);
}void loop()
{
digitalWrite(13, HIGH);
delayMicroseconds(100);
digitalWrite(13, LOW);
delayMicroseconds(100);
}The opt101 can also be connected without soldering:
