If modulation bandwidth isn't of interest, you achieve highest detector sensitivity with zero bias and high (up to several 10 Mohm, depending on the diode impedance ) load resistance. The detector output can be better processed than with the shown simplistic circuit. Specific limitations are the fixed diode bias generated by LM358 input current and the non-adjustable built-in threshold.
I guess however that the behavior isn't that bad with BAT62 and LM358.
See the attachec application note to get an idea about the effect of detector bias and load resistance.
